Hi. Earlier this month had mild pneumonia. Prescribed Levofloxacin. Bad reaction. Changed to Amoxicillin and Clavulanate. OK but stomach reaction. Felt better. Went on cruise to Caribbean. Felt fine but a little weak at beginning of week. On return, felt some chest discomfort but no fever, chills, etc. Should I return to MD to see if pneumonia returned? or should I go back on meds?
