My knees, ankles, and hip hurt. Sometimes very, very bad.?

I am an overweight middle-aged woman. I started running a few months ago and my joints typically hurt for a couple of hours after I run. I also do muscle training with a trainer and have been doing this for about 6 months and all my muscles hurt after that! LOL. Last Tuesday there was a new "event" that happened. I did not run on Tuesday, but about 3 hours after my weight training my right knee, calf, ankle and hip started hurting. Hurting so bad I thougth I was giving birth out of my knee. I took 800 mg of Advil and after 3 hours was finally able to go to sleep. Then I awoke 2 hours later still in agony. The next morning it seemed to be over though my leg felt like it had been hit by a truck. The doctor suggested that my electorlites were low, so I spent Wednesday re-hydrating and elctroliting. Then Wednesday night simarly sharp pains were back. Thrusday night, it hurt again so bad I had to sit right were I stood because I could not longer take the agony of standing up. The pain is so bad I feel like I'm going to faint. Tuesday was the longest episode lasting probably a total of 6 hours or better. Wednesday was maybe 10 short bursts of 5 minutes and Thrusday was maybe 8 short bursts of 5-10 minutes. I am on Glucosamine and ProteoPlus and Calcium and all the vitamins you could imagine. The pain feels like my muscle is being torn away from the bone and that leads to spasms that feel like little bubbles going up and down my bone. I haven't worked out, ran, nothing since before the event on Tuesday. Thoughts anyone?
