Why Have My Dizziness, Anxiety, Leg Weakness, Bloating, And Flushing Worsened Over The Past 2–3 Months?

Dear Dr. Sb AA The following symptoms have increased in the last 2 to 3 months: 1. Dizziness / Brain fog with slight pressure on temples 2. Anxiety 3. Weakness in legs 4. Bloating 5. Gas (if I sneeze, I feel better) 6. Face flushed It is difficult for me to work. Most of the time, anti histamine (kestine 10 mg) relieves the symptoms. I have IBS, anxiety, Gilbert s syndrome, vitamin D deficiency, and possibly histamine intolerance. All blood tests (CP, RFT, urine, stool, thyroid, calcium, sugar are clear except LFT with slightly raised biluribin). BP is normally low. But pulse is usually fast. I am taking 1. Prozac one daily 2. Alp 0.5 mg 1+1+1 3. Levopraid 25mg 1+1 4. Inhibitol one daily 5. Kestine SOS I have completed 4 capsules of vitamin D (2 lacs) in 1 month. Please advise. Regards
