I've had the hug, or at least I think it's that. It's mostly right side for me, pain at about heart level but obviously opposite side. I've had it before, and have been exhausted last few days along with muscle spasms in hamstrings mostly, toe spasms too. Safe to say I'm in a relapse/flare, just not bad enough that I want meds. I'm going to tell my nurse tomorrow though.
