hey bro,
eq can and will cause some joint pain, if youre prone to that. usually it happens while on though. ive never heard of any ailment hanging on 4 weeks after the drug was stopped. that being said, it takes the eq about 3 weeks to clear your system, so its possible that you still have some problems from it.
like posted above, load up on the anti-inflammatories, and keep lifting, if you can bear it. if its not cleared up in another 4 weeks or so, i'd see an orthopaedic...........
