Can Blood Thinner Cause Tingling Sensation In Breast?

I have tingling inside my left breast. It happens twice per minute. It feels like a flowing down or a tingling. There is no pain. My doctor thinks it might be hormonal related. I am 59 years old. I have Type 2 Diabetes and I am on blood thinners as I have had 2 clots in my life. Could taking too much blood thinner be the cause of this tingling?
