I've recently been diagnosed with Stage 4 Lupus Nephritis and I'm still trying to understand what changes I'll be going through. So far I've had the pains in my knees and ankles so bad that I've had injections, rashes that cover big parts of my body, and weight gain in my face. Now I've been having pain in my left hip that pain medicine doesn't really help and a rash that is causing blisters down same leg. Can anyone else relate or explain this? I'm trying to ignore the pain and live a normal life.
