Hi, I am 27 year old female. I have extreme back pains, especially around the lower back region, more specifically on the left side, just to the side of my spine, and around my waist/above my hip area. I don't think it's a cyst nor is it a lipoma, as there is nothing visible on the skin; but I can feel the bump when I press down on the area that hurts... Please could someone let me know what this could be?? It really really hurts, and I'm just hoping it's some kind of cancerous internal lump..... Thanks in advance!
