Its great your on antibiotics, Did you test your blood pressure, sometimes high blood pressure may cause this feeling, you can get a blood pressure machine in your pharmacy and test a few times when you do and when you dont get this feeling and see if its your blood pressure, if its your blood pressure it can be treated with blood pressure meds and as you get better you can slowly get off the meds, I have this vibrating feeling and my endo suggested I do Magnisum and Vitamin B6, I am taking 400mg of Magnesium Citrate, 250mg of Calcium, 100mg of Vitamin B6 and 3000mg of Vitamin D, I do see a differnce, not sure if its the B6 or Magnesium, B12 deficiany can also cause this feeling, try to get yoru levels tested, Best Wishes for a quick recovery
