I have abdominal and back spinal pain. i practice yoga three times a week and had a bacteria recently taken care with antibiotics ?

Need to see doctor: Based on the very little information you've provided my guess is that you may be having a repeat of whatever that bacteria was the first time. Perhaps, it was resistant to the antibiotic that was tried the first time especially if you were treated blindly without doing a culture. Or you could've just overdid a session of yoga...which I think is EASY to do...Have you been checked for STD's?
