If you have a health card, you can go to Hamad for examination and depending on your condition, they will refer you to a specialist Dr. in Hamad to treat you well. It's free and covered in the health insurance including medicine which you have to pay just 20% of the actual price. The amount you pay can then be reimbursed by the company you are working with. So all is free.... Moreover, it is the duty of every country to take care of its people this is the reason why embassies are here to take care of their people. The poor guy can go to their embassy and hopefully he will be taken care of.
