Has anyone here experienced (or know someone) unexplained temperature

8. She is hypo & has been on synthroid for years.

She does have some other mild symptoms
dry skin, thinning hair. No real mental issues.

She was in a car accident at age 16 & had a significant head injury. Following the accident, she had her thyroid “manipulated back into place”.

Before the accident she was 5’4” tall and weighed 110#. Three weeks after the accident she had ballooned up to ~ 140# (not fluid). So, I imagine her thyroid was damaged & out of whack in some way.

My mother took her down to a facility in Virginia Beach where she stayed for several months to rehab.
When she came home and walked through the front door, I remember being so happy to see her back to her old self. Her weight was back down too.
