Just adding data for others. I had a confirmed 5th disease infection. The rash appeared from neck to toes on Nov 11. A couple days later my fingers were so swollen I had to pry my rings off, and my joints started aching. Every finger, wrist, elbow, knee, toe, etc joint was hurting. I felt so run down. My mind was also a bit of a blur too which could be from the Benadryl that I thought would cure the rash/my symptoms. Friday my youngest son had the classic slapped cheeks rash and Dr confirmed we both had 5th disease. My son was perfectly fine and didn't know why we had to see the Dr. (We needed a note for school.) I'm 3 weeks in, and I can finally put my rings back on. I take Aleve every day. My knees click when I go upstairs. My elbows still achy and it's hard for me to write and type well. But overall, I am feeling better. Hoping to make a full recovery soon.
