Re: How does it come on so suddenly??
I would definitely see a rheumatologist or ask your PCP to run an arthritis panel for you, which includes inflammatory markers, a rheumatoid factor, a lupus test, a strept test and test for gout. This could be RA with the acute onset and multiple joints involved. Treatment for inflammatory arthritis is different than for osteoarthritis, the wear and tear type from just aging. So it pays to check it out so you can get appropriate treatment, pain control, and prevent deformity.
