Have any of you felt sooooo weak after doing simple tasks? I'm feeling that right now and I've never felt this weak before. I literally walked around Walmart to get some baby wipes and diapers for my daughter so pretty much 15 minutes tops then I drove to Costco to pick up a few items probably another 15 minutes so total 45 minutes walking/driving and I am sooooo weak I can barely talk. I feel like I can't catch my breath, the CRPS side which is my entire left side feels like there's an elephant sitting on my shoulder I can barely move that side and I feel as tho I ran a marathon or something because I didn't really exert myself too bad but it FEELS like I did. What do I do? I'm tired and can barely get a sentence out without feeling out of breath. I feel like I'm dying over here! Help say something to make me feel better please!!!!!
