i was in a mva on 2/3/13, hit on the left at about 20mph, seatbelt on diagnosed with whiplash. ended up having mri on 2/20/13 that states....at c5-6 there is diffuse posterior disc bulging and early endplate osteophyte formation with effacement of the ventral thecal sac. Impression: mild c6-7 degenerative disc disease with diffuse posterior disc bulging causing mild effacement of the ventral thecal sac. Now as for myself, i'm 33 very active/healthy no pain or issues before the accident. Headache started 3hrs after accident and hasn't ended, neck and upperback pain, shoulders, left upper arm pain and left arm weakness with cold pinky finger and tingling all started right after accident.
my question is I have a strong feeling that the insurance company (other driver) is going to see the "degenerative disc" and state pre-exisiting condition and not caused by the accident. He only had minimum insurance Iowa, so i don't want to hire a lawyer, but how can i dispute or argue with them that this injury was caused by the accident?
