Welcome in H.C.M.
I have gone through your query regarding feeling of pulse in ear and tinnitus. As you said that you can hear your heart sound in your ear , this along with pulsatile tinnitus
indicates that your tinnitus is of vascular origin.
So for treatment point of view one should investigate you for-
1- Lipid profile
2- S.G.P.T., Prothrombin time
3- color Doppler study.
(pure tone & Impedance audiometry).
I hope all above investigations along with findings of clinical examination by their clinical co-relation one may made suitable diagnosis that ay be manage accordingly.
