Oh Jenna, That's definitely not helping you feel sexy.

CRPS can spread to internal organs but before you go down that road....
Any med changes? New meds or round of antibiotics that would mess with your gut? Any changes in diet? Exposure to GI bugs?

Immune function can get out of whack with this illness and you could be more sensitive than others to environmental factors. Run through any potential culprits and see what comes up. If symptoms keep up, definitely get checked by your GP before chocking it all up to CRPS.

I hope you feel better soon!
