Hey man I’m 17 and I had stage 4 blood cancer I took radation and chemo and heavy heavy steroids and now I have Avascular necrosis in my left elbow and 2 knees and they’re saying it’s gonna collapse and I might need knees and elbow replacement or I’ll be on walker for the rest of my life , is there anything I can do about the elbow and knee pain ? Or help in any way ? I’ve done the decompression surgeries but they didn’t help they just made it worse and idk what to do man
