Hello
Howell come to ChatDoctorI really appreciate your concern, if you are not doing well and on some antibiotic it means it must be some infection is there so why you are on antibiotic, if the infection is not being eradicated or cured then it is advisable to avoid traveling by air (Clinical examination would be the last judge) if this is not the infection, and you are doing well then you can fly well hope this information helps.
