 [ Symptoms ] how is eczema diagnosed [ Disease ] i am sorry to hear you are going through this well it could be a rash or it could be a circulation problem only a physical examination by a health care provider can say for sure what is going on i would advise you to get this checked out sooner rather than later if it is a rash your health care provider can recommend a treatment if it is a sign of a larger problem your healthcare provider can get a jump on treating it which means a better outcome for you there is simply no downside to getting a doctor to look at this hope this helps
