Does anybody experience cold hands and/or feet? Sometimes the nails on my hands look like they have a light bluish, purple-ish tint to them, closer to the cuticle. The top part of the nail is normal color. When I was in the shower, I looked at my feet and my big toenail looked like it was tinged with a blue color and the skin at the tip of my toe also looked blue. I felt my toe and it was actually cool while I was in the shower! I've been through the testing for heart problems and all of my tests were normal. My oxygen level is always around 98 oto 100, even when I am in a full panic attack. I don't know if this is how I have always been as I have never paid attention until I developed HA. Sometimes it looks like I have a slightly blue line in my lips and in the corners of my mouth, even though the outside of my lips are nice and pink. I noticed that the lip thing happens to my mother and sister as well. Could this be a problem with poor circulation or is it be anxiety related?
