I met with severe car accident on 18.9.2021 while driving. I had my seat belt fastened and vehicle didn't overturn and hence  survived the accident with no serious injury,but the car got completely damaged. Now after one day,I am having following symptoms: 1)Feeling sleepy all the time. 2) Have some drowsiness and slight body pain as well. 3)Swelling in left frontal lobe of head which subsides automatically and gets swollen sometimes. 4)Slight haziness in front of eyes while reading or writing. Please advise what problem am suffering from and what kind of medical advice should I seek?
