Thanks for writing to H.C.M. for your query.
I have gone through your query regarding your nose bleed, as you said that you get little injury
in a car accident about 2 weeks back. You are also having pain on your back, neck and head.
This bleeding may be associated with your accident so it will bebetter to consult a doctor for your thorough examination and do relevent investigations to find out the real fact so that accordingly treatment may be plan.
