Should I or should I not file a complaint related to pain and suffering after a car accident?

I was in a car accident last week in which the other party have taken full responsibility. I went to the hospital the same day and refused to get an X-Ray on my left and right hand (wasn't sure if I would have to pay for it and I did not think it was broken). A couple of days later my left thumb kept being swollen and blue and hurting so I went to get an X-Ray and it turns out that I have a clear fracture/broken bone in my thumb. I am heading to a hand specialist tomorrow to see what procedures that needs to be done. I am considering filing a pain and suffering suit or complaint and the reason is 1) The pain has gotten worse over time 2) Every time I am in a car since the accident I am feeling at unease (I am still driving because I have to get to work but do not enjoy the additional stress in my life and feeling anxious) 3) I have basically 4 hobbies which are playing tennis (used to be ranked #2 in college tennis but only play for fun now), play golf, go to the gym, and play Xbox games (I know it is sad that I only have 4 hobbies) and now I can do neither, especially since I am a lefty and it is my left thumb that is broken 4) Any regular day activities such as eating, brushing my teeth, going to the restroom, etc. is becoming a challenge and it is extremely frustrating. I am not sure if I am going to need surgery, be put in a cast, or anything else yet but I am assuming I will be without a useful left hand for a while which is again extremely frustrating. I guess my questions are, how should I go about this and if I were to go forward with the case, what should I ask for? Any help would be greatly appreciated.Best Regards,A lefty without a working left thumb
