Mine are purple all the time, but occasionally my right thumb and left index turn
, although they return to purple when I press them.
So definitely this is not raynauds, is it? Am I having some kind of oxigen deprivation or circulatory problems or anything else? What tests do I need to find this out? I've had blood tests, EKG, echo, CT scan, X-Ray and spirometry. They all came back normal. Also they tested my oxygen with that device on the tip of my finger. Normal.
