Hello.. Iused To Use Methamphetamine.. I Was Injecting It For

Hello.. Iused to use methamphetamine.. I was injecting it for quite some time and have always used the same two spots in the crease of each elbow. Now, I keep getting numbness and tingling in both hands and writs. It's becoming unbearable and my left hand is worse. My thumb index and middle fingers are the worst. I also get shooting pans when I love my hands certain ways or try to push on something as if grabbing a railing to get up off the floor. The vein and my wrist swells up bad sometimes. Now it hasn't been so bad but I spent 4 hours on the computer typing a week ago and it's been horrible since then. I don't know what to do and it hurts so bad. Is this carpal tunnel or did I screw myself up being an idiot doing drugs? Please help...
