Hi there -- I had went to a clinic three weeks ago with a tight throat complaint. They had given me antibiotics as strep test came up negative. I went yesterday because I ve had swollen lymph nodes under and behind my jaw and an increasing array of new allergies (I think that s what they are) popping up. This time they subscribed 5 days allergy meds (zyrtec) and if not to go to antibiotics again. I had been taking benadryl before the recent trip and the doctor said it s not enough or not right for my situation. Right now I am experiencing the same symptoms -- tight neck muscles, swollen lymphs, uneasy stomach, yawning a lot and popping ears. These past few weeks my stools have been mainly diarrhea and i also have slight nausea. When I d recently eaten chocolate I d have awful symptoms be benadryl could t take care of... throat tightness plus stomach problems... one time was particularly bad as my muscles were shaking... maybe it was the sugar? Do I have allergies or is the medication not right for me?
