I have hip pain left and right side, swollen groin lymph nodes on left side and my pelvic bone on the left side feels deeply bruised. I have night sweats now and am only able to sleep for a couple hours at a time as the hip pain wakes me. My doctor wants to do a biopsy which is fine with me as I would love to get to the bottom of this. I am highly fatigued and have severe leg, thigh, shin, and foot pain. Both of my parents had cancer. I am currently taking 2 10 MGs of Percocet, however as stated previously, it only makes the pain tolerable for approximately 2 hours. What are your thoughts?
