Hi. First of all I appreciate all the useful, real life information I find here. Second, I have been taking Paxil for 14 years. I began at 20 mg and have increased slowly to 40 mg. I have cut down to 10 mg twice during pregnancies. Like most others, if I were to miss one or two doses I experienced unbearable headaches and nausea. Over the years I have quit cold turkey, as well (loss of insurance, etc). My symptoms of depression always came back, so I believed I was a lifer. No problem. Now, after 14 years I just feel like I'm immune. Just plain old "blah." My doctor suggested a different SSRI (Celexa), which I began while cutting back on Paxil 10 mg a week. This has all occurred in the last 4 weeks. In the past 3 weeks, I have experienced low back pain, random leg pain, hip pain, heartburn, frequent urination, kidney pain and ovarian pain. 3 pregnancy tests have confirmed that I am NOT pregnant. My doctor believes this is all withdrawl. I have never had back pain like this before from withdrawl. I am also not experiencing the headaches normally associated with withdrawl (yet). I may be a bit of a hypochondriac, but these are also symptoms associated with ovarian cysts. I have been recommended to wait it out and see if things get better over the next month. So, my questions are 1.) Has anyone else experienced back and/or leg pains and these other symptoms? 2.) If I developed an imunity to one SSRI is it likely that another in the same family would do any good? Thanks for the support and please be positive. I have enough negativity in my own mind, and don't need any more help there!
