Proving damages caused to body on later date

I was Verbally and physically abused by an act of Manhandling by a Railway employee. I also a Railway employee from Mysore on call letter from an state Govt authority was called upon for an inquiry at Hubli as there was a complaint which was proved false by me with related documents. I moved away after my inquiry but the complainant on my way out literally physically assaulted me holding my hairs and made an assault on my whole body for which i approached the concerned jurisdiction police station, where sitting for the whole day finally it was settled to take up the issue and settle the matter in presence of the Railway authorities as written and signed by both the parties due as advised by the other present employees and the police. But I travelled back to my native but now the aftereffects of the assault has started giving me trouble as I being a patient with my back spinal cord Disc prolapse with compression ahs reaccured severly with severe pain in my head for the hair pull and dragging which the assaillant had made. Now I approached the local Government doctor for report on the injuries occured to me , but he said being outside the jurisdiction he cannot record an Medico legal case for which I had to resort to only mere pain killer treatment on own. The person who assaulted me resides within my city of residence but the incidence happenned in another city. Kindly advice me how to deal the issue now as after a day I am being aware of internal damages occurred to me. How can I prosecute and whom all should I represent.
