I am not used to going on forums. I was diagnosed with Underactive Thyroid about 2007, since then I have had a benign brain tumour (melingioma) where my brain joins my spine. Could the operation have damaged by thyroid gland. I am now classed as elderly (76) so will the problems get any better. I am still putting on weight, hissing in the ears, tired, eyebrows nearly gone, nails breaking, migranes etc Last time I went to the doctor, he did not seem to be interested. I don't know who to talk to.
