I have been dealing with two symptoms for the last several years. I've had fibromyalgia for about 25 years, but only recently have I developed a hoarse voice and periodic itching. I've consulted more than one ENT doctor, and as a result am on Mucinex, but I remain hoarse. There is no systemic reason for my hoarseness. I do have a thryoid problem, but am on Synthroid. And now I am once again itching, on my arms and legs. I'm convinced this is fibromyalgia, but I don't know if this is a common condition shared by others. Is it?
