Hi I'm 25 and just been diagnosed with severe endo after having a 15cm chocolate cyst out. I've suffered with lower back, hip and knee pain. The back pain is the worst reducing me to tears when walking or standing for more than 5 mins it feels like my bones are crushing. is this due to endo? And also I'm on tramadol and co codamol for the pain these aren't working is there anything else I could take to help.
