I meant to write earlier about the doctor's visit. It was fine. My doctor didn't feel any nodules on my thyroid, but did write a referral for me to get a sonogram. As it turns out, I've been on the wrong dose of my thyroid medication for months. My fault. I was able to get sample packs of the medication, and I asked for the wrong dosage. My doctor thinks that might be the reason for the problem I've been having. I had blood work done today, and I'll schedule the test. I do feel better.
