Raynaud's Phenomenon Getting Worse - Need Help

I think my raynaud's phenomenon is getting worse. I can't touch anything cold without my hands going numb and turning colors. not only am I having problems with numbness in my hands and feet but most of my body as well. I don't know if this is part of raynaud's phenomenon or not but now when I get in the shower I cannot feel anything. The last couple of days I have gotten out of the shower with scorch marks on myself. I can't tell when the water is too hot either. Right now I am only taking a baby aspirin every night for my raynaud's phenomenon. What helps you? is this heat part of raynaud's phenomenon or something else? I know I need neck surgery again because I also have degenerative disc disease and a screw from my previous surgery has backed out some. This might have something to do with losing some feeling in my arms but not the rest of me. Any help would be appreciated. thanks
