I have been a chronic user of crystal meth for the past 6 years. In 2006 my doctor told me that if I do not stop using I will develop Congestive Heart Failure because I was showing the symptoms at that time. Well the symptoms are back now and more severe than before, with my feet and ankles swelling to almost twice their size and my breathing has become extremely difficult to the point that I wake myself up from sleep if I shift into a position which causes more stress. I know have a pain in my lower back that keeps me from being able to sit up right without almost crying out in pain. Are all these symptoms due to my meth use? I've quit using just recently, but the pain in my back seems to be unbareable.
