Not sure. I am not sure what you mean by thyroid of 10 that could be either very normal or completely abnormal. The thyroid that needs to be below 4is called tsh, and the one that needs to be around 10 is t4.
Thyroid control. If your TSH is 10, please see your doctor to get it under control as that may help.
