I have arthritis in a toe and some fingers. Actually, coming from a dryer climate, I actually feel better in the higher humidity levels. When we have lower humidity readings, that's when I notice the affected joints.
The humidity here doesn't seem as oppressive as it is in other parts of the state. I do recognize that some people have more trouble with humidity impacting joints, for me, it's always been the opposite. I can actually tell when humidity levels are getting lower....dam toe lets me know...
