Hello I am recently on the withdrawal period from meth, it is not as bad since I have not done large amounts in a short amount of time. I been doing it for about maybe a month or a little less. And now in the fourth week after starting to quit I have noticed that after playing rough, fast, and 6+ hours of tennis every day, that my right knee is kind of hurting when I fully extend my leg to either run or walk. What could it mean? Also my Achilles tendon is having some pain, not too much. As well as the middle top of my foot? What can I do to recover???Also, since my teeth feel like they are losing a little bit of strength should I consume milk, calcium supplements, and any other dairy to repair them?
