My 28 yrs old son has suffered severe pain due to herniated disc, but after MRI doctor said he has abdominal abscess in his lower spine between disc, they rejected to do biopsy to determine what type of bacteria it is as risk is too high than good. Now they treat him with cloxacillin for 6 weeks which I think is a very long period of time to take antibiotic, very worry that there would be side effects that would cause life time damage to any of his organs. Is there other kind of treatment that might has less side effects?
