Has anyone with Thyroid/Parathyroid issues expienced falling off, brittle toenails?
I've lost about 60% of my hair and now my toenails are brittle and some falling off; I also have ongoing night foot muscle spasms. Thyroid results (TSH, FT4, antibodies) are normal and I did have a slightly elevated PTH in the past. Any thoughts on what would be causing these symptoms?
