Question: Can allergies occur w/no outward symptoms of sneezing, runny nose/eyes, etc? Also could they cause feeling of choking and fluid on back of my head?

Can allergies also cause slowed digestion? And how do i find out if im allergic to certain foods or my dog? Ive been tested for dog in general but not my soecific dog.

I am having tingling pains in my head, headache in back of head, hair hurts and a constant feeling of fluid flowing down my throat. Also having difficulty with chronic constipation, reflux. All of this came upon me during, and after, 3 rounds of shingles from July -Dec and has continued to make me miserable long after the shingles rashes are gone.
I have No typical allergy symptoms. My allergy testing for dog, in general, was negative. My dog is a shorthaired, red, female Doberman.
I did show slight reaction to dustmites, mountain cedar and juniper, but none severe. I do, however, live in the mountains of NM surrounded by all the above items and have lived here for 10 years now.
I appreciate any enlightenment you may offer me. i am literally beginning to question my sanity, but these pains and symptoms are really happening and i cant get relief. Tried all nasal allergy sprays, neti pot, steam, allegra, benedryl, claritin to no avail. Accupuncture gives some relief for day or 2, as does sucking on lozenges but nothing makes this flow and pain go away.

I am self employed as a pilates trainer so im in an office studio. I live in the mnts. Of New Mexico at 7000 feet surrounded by pine and cedar forests. I have seen ENT who says nasal/throat clear. Xray & CT Sinuses w/in normal limits w/small R turbinade and no sinusitis. I am wondering about viral allergies. Ive read viruses, like shingles, can cause them. What are your thoughts. My head & neck hurting & the constant flow down throat bring up anxiety for me and has made it hard to function normally. Migraines? I just am baffled & frustrated.

1. I have pain in my Cervical spine, On Left side, and pain in my mid thoracic region posteriorly which feels nerve-like, stinging/burning. And when I lean back on something like recliner, car seatback, the flow feels like it increases as if it is coming up throat from below. This pain is pretty pervasive, as well. I also have some pain in front just below sternum and in on left side rib cage.

2. I had EGD in Dec. 2014 at Mayo clinic which they said I have 2mm hiatal hernia and that it should not be causing me troubles. No H-pylori, neg. stomach biopsy, but some fluid in stomach and esophageal reflux/globus. They also gave me Advair and Albuterol for what they called a-typical asthma, whatever that means! I use Albuterol as needed occasionally and it is one thing that does seem to help open airways and give some relief. I have not taken the Advair because I am really having difficulty going from a strong, healthy woman to someone needing to take all kinds on drugs w/their own side effects. I know asthma can improve w/biofeedback, relaxation and exercise, all if which I'm doing more of but still no change.
2a. Had colonoscopy in 2010 and it was clear of polyps, but some diverticuli, and more intestinal folds than typical.

3. I have been taking 1 Prilosec 20mg, after evening meal, since Dec. along with
1-2 Gaviscon before bedtime. Probiotic daily as well as digestive amino acids 2x/day before meals. All to no avail. I just can't seem to get relief and it's taking a terrible toll on my attitude and life.

I do not really seem to have any more or less pain after eating. As I said, it is pervasive no matter what I eat. I never truly feel hungry anymore but I do make myself eat because I need to. Also, eating seems to stop the flow temporarily and makes me feel better for that time. But then it comes right back. I eat 2-3 small meals per day. Lots of warm fluids and water.

So I have had much expensive testing, they gave me scripts which I have followed and nothing seems to be getting better. I have changed my diet, cut out coffee, soda, sugar(mostly), eat a lot of soups, warm stuff feels best, but am getting no real relief?
Is it possible to have reflux so bad that I am actually allergic to, and aspirating on, my own digestive fluids? And if that is possible.... What can I do about it? This is truly a miserable way to exist and I'm beginning to feel hopeless. I appreciate if you have any helpful recommendations. Thanks.

I have been a relatively balanced, healthy and happy person up until these shingles occurred from July to Dec. the pain & other symptoms of nervous system feeling off kilter, nausea, vomiting, difficulty breathing and severe constipation/digestive issues, headache and nerve pain that grew more intense w /each bout, and now seems that some of those symptoms have become permanent. I do know i am feeling anxiety and some depression now but i did not have them prior to all of this. We do not lead a stressful lifestyle. If anything, our lifestyle may be a little too laidback and quiet for me . We make ends meet financially, i have a very supportive, loving husband and family. Something that has been stressing me is comming to terms w/aging & ailing parents, seeing friends of my same age getttin ill & some dying unexpectedly. That has been my biggest stressor w/in the past year.
If You belive this is Gerd, not nerve or shingles encephalitis, . would it cause the chronic headaches , nerve pain and flow in the otopharyngeal area ? What would your treatment recommendation be since Prilosec znd gaviscon are not really making any headway? Would you suggest i try the Advair along w/Prilosec and gzviscon? Could thiese treatments actually cure thungs or just manage them? what are long term side-effects of these treatments. And are there any more permanent options , like surgery? PleAse tell me your recommendations. I really need to get some relief. How do you feel about anti-anxiety or anti-depressants? I dont want to mask symptoms as they continue to get worse but i need some relief. Thanks again.

What are anxiolytics? Is that like Xanax? Are you suggesting that the pain is creating the anxiety/depression or the anxiety/depression is creating the weird pains? Because, as I said previously, I wasn't depressed/anxious until the shingles and their complications. I have never been to a psychiatrist and will consider that after ruling out all physical possibilities first. I'm not against the use of those types of drugs but I do believe they mask symptoms without healing them. It's possible that's what I need right now.
I realize this next question would be a rare thing, (but the word rare means that it does actually occur at times) is it at all possible that this could be a CSF leak brought on by the shingles, or the fact that I live at high altitude? How would one be tested for that? Thank you.
Thanks.

Thanks for your quick reply and all of your help thus far. I do agree that I am having anxiety/depression but as I said it wasn't until after the shingles seemed to bring on all of these weird symptoms.

I realize CSF is rare, however, do you agree that some of the symptoms I am experiencing could be indicative of CSF leak possible brought on by complicated shingles and/or high altitude living?

I appreciate your input. Thanks.
