Help. I have never been diagnosed for an autoimmune disease. About 3 weeks ago I decided to try Juvederm. Now that I think back to the date I had that injection I realize not long after I thought I had the flue, or a sinus infection. After 2 weeks I couldn't take it anymore I felt drained. I went to the doctor and and I never thought to mention that I had Juvederm. He said 14 days it was probably turning into a sinus infection and I left with some antibiotics. I just never felt like I was getting better and my stomach always seems to be cramped up. I also wake up and my index finger feels like someone took a hammer to it while I was sleeping (it hurts like that) it feels better as the day progresses. But it feels stiff. I usually workout out 6 days a week and right now after I take a shower and get ready I want to cry because I just want to go back to bad I feel like something is in my blood. Has anyone felt any these things?
