### input:
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?

### output:

An uneasy stomach, diarrhea are adverse effects seen with antibiotics course. You may want to have a probiotic supplement like yogurt or Yakut to correct that. Swollen lymph nodes along with hypersensitivity(Allergies) may be due to a viral infection that cannot be cured by antibiotics. Unfortunately for viral infections all we can do is give you supportive therapy i.e. an analgesic for pain, an antipyretic for fever and some vitamin tablets to counter fatigue. You have to let the body fight back the viral infection. Thank you for your query
