I am having a time tring to find info on the two. And well, since so many of us are either on or been on drugs in the past thought maybe someone could shed some light. No secret I abused alcohol self medicating. No secret I used to take 9 - 10 mg xanax a day. But when coming off I had so many different pains but one is sticking out now as I am not going through withdrawals at this point; I can't with DH laid up, only one adult screwed up in the home at a time so I am maintaining the 3 mg until he is up and about again. They are still keeping me on the 50 mg zoloft until off xanax then dump the zoloft. Thing is I had started to get some good kidney pain with withdrawals and now it is not stopping though all the other uglies of withdrawals have stopped for the most part, so now it is sticking out like a sore thumb. They started zoloft when they started the cut in xanax. I will be seeing my GP when my husband goes back in to ask but in the mean time I am starting to pass blood like a kidney infection. (down side this is the doc who had me on the high dose xanax) But as long as the pain was there and an infection (I have had a few infections there) the blood seems like it would have started a lot sooner. Though it is is acting all too much like an infection it just seems like it has gone on way too long to be one. Anytime I had a kidney infection when the pain started I would be stuck in a hospital within a week of pain out of control getting IV treatment for at least 24 hours. Anyone have a clue what gives? My husband said if it was jacking with the kidneys wouldn't it have been so during the high dose? I would think so, but considering it was such a high dose I may not have felt it... Or is zoloft the culprit for the last 2 or 3 months? Also, I feel it on both sides of my back, not just one side like I would with a normal infection. I know not the normal PTSD questions, but since most of us have been on the pill happy highway at some point maybe someone has experience with this?
