Do not be desperate. Take your time to plan and gather the resources you require without haste. After all, free medical clinics are usually money-making schemes, where the medics suggest all varieties of tests just to make some money from you at the moment, and later as a patient. It could also be that you have done some of the tests before, but they will still insist on fresh tests. Something else, consulting this specialist outside the 'free clinic' is not that cost prohibitive as you might imagine. And these clinics will keep coming up. Continue searching for upcoming clinics everywhere and also compile a list of sources/specialists you think might be of help.
