Erin,

I know I haven't been on for awhile but I saw this and HAD to reply. I too get serve leg pain and up the arm on my left side. I saw my Dr. just this week and he feels it is side effects of my meds, or bad disc in my neck. Since all of it started with my meds, I am saying side effects. Now your swelling.. not good.. need that checked ASAP. I have some swelling but not bad like you.

All my blood work comes back fine.

Please keep us updated.

Big Hugs
