It's kind of hard to tell the difference between inflammation and a flare because they feel a lot alike. I think the biggest thing is inflammation calms down faster, usually in a day or two. A flare may take a week or two to calm down for me.

Nerve pain for me, is usually more of a burning feeling and a lot of times I get some tingling in my hands. If I have inflammation, or nerve pain or tingling, I usually let it calm down before I exercise again. So when I feel good, I do more, and when there's pain, I don't push things too much. I keep my movements a lot more gentle.
