Rho,
Discontinuation of Paxil is generally well tolerated when tapered appropriately as in your case. Flu-like symptoms such as muscle and joint ache, nausea, fatigue etc... are sometimes experienced upon sudden cessation of Paxil. Symptoms may persist for a few days or couple of weeks but I have never heard of withdrawal symptoms for a months duration. The symptoms you describe are probably not part of a discontinuation syndrome. I suggest further medical evaluation for a different etiology.
Sincerely,
HFHS MD-JM
