For over two months I have been having pain in my lower back, buttocks and hips. I found a small lump in the beginning, now it is about the size of a golf ball and now I have three others which continue to get bigger. The biggest one feels like it is right on top of a bone, it doesn't hurt when I touch it but hurts after I quit touching it. Now it hurts to sit, lay down, and walking. Also this may not be connected but I have lost about 30lbs over the past 8-9 months without trying to. Can someone please help me figure out what this could be. I am scheduled to go to the doctor next week, but I dont have insurance and probably wont be able to take the tests he orders.
