Had my dosage of levothyroxine reduced from 100mg to 75mg, now back to 100mg.
When I was first prescribed levothyroxine, I noticed my 2 toenails on each foot, next to my big toe, fell off, but they grew back.
Now my middle 2 toenails are starting to do the same thing.
My question is, could it be anything to do with being under medicated?
