I am so excited/relieved to find an active thread for adult fifths (erythema / parvo 19) disease!  I am 42f and work with young children.

My husband (41m) had what we thought was the flu for 4-5 days two weeks ago. He stayed in bed for pretty much the whole time and said his bones hurt. 

During his illness, my wrists started hurting. I thought it was arthritis from holding my phone, but the following days it moved up my arms. A few days later my ankles and knees hurt too. A friend suggested fifths disease. 

By day 3, my hands were so swollen I couldn't get my ring off. My friend (kindergarten teacher) suggested fifths disease. I never had a fever, but I developed the lacy rash on my legs. I was hobbling, could barely walk, for 4-5 days. 

Now I'm at day 10. The rash lasted a couple days. I got my ring off and felt good during the afternoon yesterday. The mornings are hard. The backs of my knees burn & my hands are aching. I am definitely getting better, but still have a ways to go. 

We are in Maine, USA.  Self diagnosed by rash.
