Hi Beaker, my pain is all one one side too. I have pain in my groin and all down the front of my thigh, right around the top crest of hip bone and right around the back. The pain also travels down the leg into the join of my foot. I described it today to my husband as like an elastic band that was being twisted tighter & tighter. It's so upsetting to go back to this pain after being pain free for 9 months. I have stopped taking the antibiotics and decided to get some cleanser & cream from a company called Kalme. I hope it works. I did some more research and have found that the antibiotics can have an effect on some women who take hrt. Maybe I'm just unlucky. Also I did have a really heavy cold for a while. Apparently that can also have an impact on some women. Again, maybe it's just me. I just want to be pain free again.
