In reply to SSRI's and permanent side effects, posted by Mary on May 2, 1999, at 3:26:31
Mary, the combination of Paxil and Zoloft could cause something called central serotonin syndrome, which is what you're describing. Some of the symptoms are nausea, diarrhea, sweating (like, your clothes are soaked through), tremor, chattering teeth, muscle rigidity, myoclonus, ataxia (unsteady gait), and confusion or delirium.
It's rare, but not unheard of, to hear of such a bad case of CSS that doesn't involve a monoamine oxidase inhibitor. It may have been more serious because the error was not discovered sooner (so that you kept taking the medications); also, 40mg of Paxil is rather high (10mg is a common starting dose). The mechanism(s) of this syndrome are not well understood.
Though CSS usually resolves within a few days of discontinuing the offending drugs, I *have* heard of one case of long-term sequelae - specifically, extreme rigidity.
I think that your chronic symptoms may conceivably have been induced by the combination of the two SSRIs, but probably not by the abrupt discontinuation (although you do describe common SSRI discontinuation symptoms, in particular the "electric shock" sensations).
Here are a couple of references to articles that mention SSRI-related or -exacerbated movement disorders:

I'm sorry I can't offer more constructive help. Good luck with things.
