My daughter is 16 and has been experiencing a condition with her feet since she was 13 or 14. In the winter (i.e. when it's cold) her feet turn to a bright red, then a dark red and sometimes purple. She experiences pain - sometimes severe - and numbness. During this time, she also gets what appears to be a rash on and slightly in-between her toes that itches, hurts and eventually peels off then comes back. At first, we thought the discoloration was because her feet were simply getting cold, so we had her wear thicker socks. While this does alleviate the symptoms, the never completely recede until warmer weather returns.
We have taken her to three different specialists, one orthopedic, one cardiovascular and one orthopedic specialist that specializes in feet. Through a barrage of tests, they just say "well, we can't find anything wrong ,just keep her in thick socks." This seems to be treating the symptom and not the cause, and has moderate results at best.
More information: My daughter is a fair complected redhead. Average/medium build, but not "athletic". No signs of diabetes or any other assignable medical affliction.
I'm not looking for an online diagnosis, I'm just seemingly out of options for where to go from here. I hate seeing my child in pain, and the only treatment is wearing several layers of thick socks. What I am looking for is maybe a different direction. Any feedback is appreciated.
