What Does My Thyroid Function Test Report Indicate?

For the past couple of months I have been having problem with hair loss. So much so, it comes out a lot when I shower and comb my hair. Like I said this just started a few months ago. I checked all my meds and atenolol and amlodipine can cause hair loss. I had a thyroid blood test and it was normal. I also read that physical and emotional trauma can cause hair loss. I did have a knee replacement last year and schedule to have one in Sept. I do have other physical concerns, and they are being addressed. I am planning to see a dermatologist, but until then I am worried sick.
