For the past few days I've noticed a cold spot about the size of a big coin on my inner thigh. It comes and goes and feels wet and cold but obviously nothing there to see when I look at it. I don't think I've damaged my thigh in any way. I'm now worried I am going to develop an awful neurological condition (I don't think I have health anxiety but I work in healthcare so do see some awful life limiting conditions). Googling is a bit scary so thought I'd post here for traffic if anyone has similar. Thanks
