Hello everyone
My sister was diagnosed with hypothyroid about 5 years ago. She doesn't take any medicine for it. I don't know if this has anything to do with the thyroid problem but for about 3 months now shes had this skin discoloration on her throat and its really scaring me. It looks like someone took black eyeshadow and put it on her throat in the center about 4 inches long, up and down. She has an appt with the Dr next week. But I'm worried till then. Does anyone know what this could be? Any suggestions would be greatly appreciated...
Thank you
