Hi. Im a 29 yr old female and I'm 5'7. I am currently on blood thinners for blood clots within my lungs. I hit my head really hard about a month ago and I just felt really uncomfortable. I went to the ER they checked my vitals along with x-ray but did not do a cat scan. My INR came back normal and I did not have a sever headache or anything, but lately I've been feeling very uncomfortable. My head doesn't hurt bad but I do get dull headaches from time to time. When I sleep I wake up and depending on how I'm laying my arm may go to sleep freequently or when I'm doing anything rather my arms and legs have been going to sleep more than usual. Sometimes it feels as if my head weighs a ton and I just feel uncomfortable and anxious. Should I go back in to the ER or am I just really paranoid. I worry about internal bleeding
