Suggest Treatment For Multiple Ailments

Hello,
I am a 52 yr old female. I have 3 kids and am happily divorced 90% of the time.
I walk a couple of kilometres a day when I can and do my own housework.
Do ballroom/latin dance lessons 1 - 2 times a week for an hour each and dance every opportunity at home :-)
I don't use any medication except Natura homeopathy meds when I remember.
I had a severe bout of gastro on Friday and was put on a drip and given a script. I completed the anti-biotic and used the other meds when needed. Slept a lot. I am fine now. BUT....
I have been experiencing....
1. a 'tingling' down my arms, legs, and lips. Not all at the same time.... comes and goes and is not severe.
2. very slight pains in my upper arms and chest into my neck and jaw. more like muscle stiffness.
3. am gassy / burpy and yawny and feel bloated (can it be from the drip?)
4. tired. have been exceptionally tired like deep weariness I put down to being miserably down in the dumps over a 'break-up with a boyfriend and also not eating correctly. yet I just dont sleep.
5. The ONLY problem I really have is a 'slipped disc' in my lower back - have been to physio and MUST do tummy exercises for the rest of my life to strengthen muscles.
6. I get cold then feel like its stuffy and I'm hot
7. feel light headed.
right now theres a weird feeling like the muscles are gently tightening down the left side of my neck
Ok I sound like a crock hahaha am also wondering whether I have perhaps caught nerves (thinking slipped disc) with all the vomitting on friday
Your help will be appreciated thank you. Margy
