Thanks for the advice gmcraft!

So, according to the doctor the above mentioned suspicious looking points are RT side effects. He did a physical examination by pressing the mylohyoid area, he said it seems clear as of now. He asked to come back again for a checkup after 3 months. I want a second opinion though.

I also had another conversation with dad about alcohol and he said he'll quit altogether. I told him if he can do that then that's great otherwise start slowly. Reduce the frequency and gradually get to the point where you don't feel like having it. He seems on board.
