Hrt

Been on HRT (oeostregen only) for just over 2 months, for the last week or so my left breast feels sore and sometimes I feel a tingling odd sensation, went to doctors no lumps/bumps found but keep worrying. Anyone else had this problem? 

My breasts were very sore until I few days ago, I to have been on hrt for 2 months , its just one of the side effects i think.

Thank you for your post makes me feel I am not alone with this and it is normal.
