Blood pressure and pulse sometimes high. blood tests and ecg ok. also anxiety. could thyroid be cause? long family history.

Could be, but: I assume your thyroid has been checked already if you say your blood tests are normal. Are your blood pressure and pulse high when you are anxious only or also at times when you are relaxed? Are you doing something for stress management? Meditation, for example. Qi gong has been shown to lower blood pressure, as have deep breathing exercises.

See MD: You need to rechecked by md.Ask questions.Can be thyroid.Need further evaluation before any treatment can be given!
