Good luck! I know how stressful tests can be, but I don't think you have anything to worry about. I know I mentioned menopause in an earlier post and you said you'd been through it - my mom, 64, still has occasional symptoms even though years post menopause. It's not uncommon. However, like you said, that's also a symptoms of anxiety. I felt things crawling in my hair the other day, too! It seems to come around that time of the month for me as I'm in peri. However, I also work with children and worry about lice a lot! SO that being said, I think sometimes I just think too much about it! lol!! Take care!
