Suggest Remedy For Shoulder Pain And Severe Headaches After An Accident

In march I was in a MVA, I had a concussion and neck strain along with severe twitching in my right hand, mainly the middle finger, since then my finger has become partially paralyzed and my forearm left with a feeling of tired as if there is no blood going to it, my gains are always poking out now also as if in a tourniquet, severe head aches and major shoulder pain. The biggest issue is the fact that I know it sounds crazy but for almost two weeks now I have not been urinating, I mean it s as if I ONLY go when my bladder fills up so much it leaks out, almost like my body isn t telling me to use the toilet, the sensation just is NOT there any more, therefore I am urinating the bed. I see a chiropractic 3 days a week due to the MVA but I don t think it s targeting the REAL problem, HELP ME! It s to the point where I can t even hold things and I find that I trip a lot now when walking.
