After injecting several doses of Meth Amphetamine (approx. 30 units each) over the course of several days I began to notice localized swelling and edema to my right knee which was also accompanied by redness and slight warmth. I do have a pmh of chronic gout. I am 39yrs. / M / 175lbs. Is this caused by an imbalance of purines in my system or is it more likely to be the result of dehydration??
