Hi, I am 28 years old female. Since few days I had neck shoulder and arm pain, as it sounded scary because I had pain in my left arm I consulted the doctor. He said I should take blood thinners without even checking. So I did an ecg today ad the report said sinus rhythm and inverted t wave (v2. If I rest and not really study alot or jump around and just lay down reduces by itself. But when I sleep and wake up at night it increases. Kind of like due to wrong posture thing. What should I do? Should I consult a cardiologist? I have heard if you once start taking blood thinners it forever.
