I've been suffering a lot with backache. I've done countless physical therapy sessions. I've consulted dozens of doctors, including orthopedic surgeons, neurologists, rheumatologists and physiotherapists. I've tried all kinds of anti-inflammatory drugs and painkillers. After knee surgery (meniscus) the doctor ordered as a precaution, [B]Cephalexin 500mg[/B]. Amazingly my back pain disappeared almost completely. According to the doctor there is no relationship between the medication and pain. The fact is that my pain stopped. Does anyone know of any study on the use of antibiotics to combat backache?
Welcome to the board. I think it is more likely that the surgery on your knee resulted in a change in the way you are using your back, its structural alignment, whatever compensations you might have been making due to knee problems, etc.
I've never seen any information whatsoever of an antibiotic resulting in less pain...and I can't see how it would affect most issues that can cause backache.
