Does anyone know how long fifths disease can last? I guess I had parvoviurs because I'm an adult and my kids had the fifths disease part. So, if that has been my problem all along, can that be right? It's been over a year since I had the joint pain that went with the fifths. I had it again recently. I thought I had Ra. But it's almost gone now. Well, mostly all gone, just hurts once in a while. I'm wondering if anyone here knows about fifths disease and can it last this long and be cured? Thanks. If this is all I had all this time, well, I'm thankful, but I'm mad at the docs for not realizing it. I told one that I had fifths and never felt right.
