You say you are an EMT and they don't offer insurance with your job. Are you part time? or did you just opt out of it. If you can get covered under a group then the pre-exisiting is usually waived.
I agree, this could all be coming from the liver. Please see someone. There has got to be clinics around that will charge according to what you can pay. Or somehow get the money from family or friends or borrow. Not much important if you don't have your health.
