My pain originated in my lower abdomen 3 years ago then went to the backs of my knees, then my hips, and now laying in bed it feels like the fluid in my joints in my knees is boiling hot, and travels up my quadracepts and into my pelvis. This happen to anyone? Whats weird is that on the chart that shows where the pressure points on the human body are there arent any shown anywhere near the pelvis or lower abdomen-- or for that matter the back of the knees. So thats leads me to wonder if i have been midiagnosed. Any Ideas? Similar pains in that area? Also have enflamed lymph nodes in my lower abdomen right about the area of the pain. All tests negative of course... so what is the relation with fibro and enflamed lymph nodes?
