Hello. I'm Really Confused, In Pain And Very Uncomfortable. My

Hello. I'm really confused, in pain and very uncomfortable. My left knee is frozen at about a 45 degree angle and feels really "full". My left calf muscle is really weak and when i try to tighten it, it doesn't tighten like the right. My left elbow and forearm are the same. I have pins and needles sensations and nerve pain as well. I had Rhabdo 3 years ago and wonder if it's related. I haven;t done any strenuous activities to injure the muscles. Docs did Lyme testbut was neg (I'm on Doxycycline and have been 10 days) CPM and CBC were all normal too. Is CPK included in any of those tests and what avenue should I pursue to try to get to the bottom of this? It seems to be getting worse each day. I'm 31 years old. Alsop have diarrhea, fever/chills, stomach ache and nausea.
