 [ Symptoms ] i have moles and freckles and worry about getting skin cancer should i see a doctor i do not have health insurance [ Disease ] i am not able to tell what might be going on particularly since you have had quite a few tests in the past your condition is too complicated to figure out without the benefit of examining you you need a doctor to examine you and i would be concerned particularly about the shortness of breath and paintightness that is not something you should ignore i assume when you had your heart checked it was because of these same types of symptoms however they should still not be ignored and you should give your doctor a call
