What Causes Dizziness And Hypotension Along With Redness On The Hands?

Dear Doctor, I am a 30 years old male who is really suffering from the following symptoms: 1. Black color under eyes 2. Red hands and feets (feet toes more and during washing my hands red spots appears and disappers after a minute but still you can find some reddnees on hand toes) 3. Low blood pressure 4. Lightheadeddness 5. Loss of weight 6. Feeling like my neck muscle is blocked and cannot swallow a pill easily 7. Light red and yellow color in my eyes 8. Light pain in stomach from time to time and maybe in the liver too or intestine 9. Lack of RBC and WBC according to blood test done 2 months ago Noting that I am really passing by an extremly high level of stress since 1 year and still. And I take hot sea water bath from time to time and was following a strickt diet thinking I have diabetes or gout or being gluten allergic but that diet led me to really collapse and made me hungry for regular food. I was doing hight intesity workout exercises for more than 3 years I should add that I am taking 2 medecins: Magne B6 and Co Q10 thinking it might help abs it really helped pass from a severe level to a less severe one. I d really appreciate if you can help/guide me in my case, it will help me a LOT. Awaiting your valuable and prompt reply. All my respect, Elie More details about the presenting complaint: I did a blood and urine test 2 months ago. Fyi I realized I am loosing blood, I checked my stool at home, its color was black and smelly so I realized that there might be an ulcer and it s at that moment when I decided to follow a diet based on greens and beans to stop it and yes, the stool color changed and no blood in my stool and even the smell is so low. Btw I did the test since I was really concerned about being diabetic and still actually. Previous history of the same issue: No previous history Current medications: Coenzyme Q10 Magne B6 Past medications of the same issue: I was taking Becozyme, it was recommended to me due to some mouth ulcers, my pharmasist told me I am allergic to nuts. But I stopped it 5 months ago and when I eat nuts now, no ulcers appear and that s weird. Lab tests performed: Before doing the blood test, I stopped exercising and started eating to gain weight since I was and still loosing and I realized during that period of 1 month, hurting and burning sensation in my stomach and liver, and at excessive peeing at night (more than 5 times) and a taste of metal in my mouth at night. That s why I thought it might be diabetes and did the test.
