injecting methamphetamine causing uncontrolable cracking

[cleo85]

swim injecting base(meth) for bout 6 1/2 yrs and swim wasnt the most sanitary person for the 1st 4 yrs,while swims veins r paying the price for it now,swim suffered blood clots for a while but now for the past 1 1/2 i the clots have gone but even though swim use less often and less amount swim seems to be suffering from sum sort of arthritis.after a few hrs after they had they start to uncontrolable crack their finger, knees and feet.sometime swim get these big bruised lumps where the joints r.swim is just wondering if anyone else is having the same problem.swim just dont understand how they r having this sort of problem when they r alot cleaner with it and dont do it anywhere near as often.shouldnt it be the other way around..anyway i am new at this whole forum thing but if anyone can shed sum light on this situation for me that would be great.
