I am 64 yrs old and I was diagnosised with sarcoidosis in 1987. I am having trouble regulating my body temp. I and cold all day no matter the outside temp and at about 10 p.m. I get hot and sweat all night. I am taking prednisone 5 mg daily, neurontin 60 mg 6 a day and thyroid med. I don't sleep but about 4 hrs a night and I don't take naps. Do you think this problem is sarcoidosis ot thyroid? Is there a specialist I should see?
