Costs with medical tests/treatment

After a couple very scary health scares in the last year,  it appears my condition is getting worse with deteriorating problems over the last month.  Very invasive testing is needed to finally, once and for all, figure out what is wrong with me medically.   With this comes great costs being uninsured.    And due to these health conditions I've barely worked in the last 5 months or more.   It is with hat in hand that I hope my friends will help as my family is already doing all that they can.
