### input:
Was in a car accident 6 weeks ago and had severe bruising, my first CBC showed my hemoglobin to be 125, and the second (a few hours later once the bruising really set in) was 114, and they said 112 was problematic since the car accidnet i have been very tired and sleeping, a lot even for me, but i also have a concussion . My mother just recently had to have a unit of blood as her hemoglobin came back at 79. when i saw a doctor he said i should be fine as my color was good, and my bruises were going away.that if i was having problems id be more tired than i was. Im still having slight paliptations, and fatigue , and my heart races quickly, but they dont know if its due to anxiety , concussion or hemoglobin. I dont see how it could have gotten worse but im scared something is wrong. How long would it take for my hemoglobin to go back to normal, and how could i tell short of getting blood taken and waiting a week for the results.

### output:

Hello and welcome to Chat Doctor, There is blood loss in road side accidents (RTA). This blood loss may be external or internal. Bruising indicates internal blood loss. It leads to fall in hemoglobin. The fall in hemoglobin levels leads to symptoms of tiredness, weakness, palpitations, etc. You need to get complete hologram done. Any abnormality in level of hemoglobin, red blood cell counts, hematocrit, RBC indices - MTV, MCH, MCHC can be detected. In case of anemia (low hemoglobin) appropriate treatment can be given. Thanks and take care Chat Doctor.
