I have been sick for 4 weeks and now on my 4th antibiotic i started off with a kidney infection and then went to sinus infection and then went to bronchitis and now back at a sinus infection and now I'm on doxycycline 100mg 2x a day and I'm scheduled to have surgery on May 28 and i still have congestion in my head but not much left in my chest do you think its a safe go to have my surgery as scheduled since this is the 4th time of being rescheduled from all my illness and I'm not running any fever just normal sinus problems?? Please help!
