My arm "event" was over 2 or 3 yrs ago. Just before my neck started to have arthritis too.

I attributed it to "sleeping on it funny". It didn't hurt or tingle either. Just couldn't move it.

Now I have this left ankle swelling now and then. Just got over a 2 day swelling event (this is very uncomfortable and somewhat painful). Doctor is stumped. I don't get it on vacation, and it takes a while being home before it returns. I think it is from climbing stairs (no stairs on vacation). (it is my old surgical foot that had the instep tumor removed 50 yrs ago! ) Rubbing on magnesium lotion seems to fix it too, so far.

I am going to be 66 next month. Some days it seems everything is falling apart.
