He needs first of all to be stabilized and get an accurate diagnosis. Dr. Hector Ortegon at Clinica Merida is a neurological surgeon. They can do MRI's and other tests there and if surgery is indicated, Dr Ortegon can do that. His cell number is 9999 471014 and what ever country code before that---I think 044. The cost in Merida is much less than the US and the treatment there is good.There is also the cost of transport. To send him to the US would cost more that $20,000 air ambulance and you could get a private driver to take him to Merida on a stretcher for much less if his condition is stable.
