Losing Feeling in Legs and Arms Nothing Shows in Tests

My wife had a bug a few weeks ago (we all caught it, brought home by our 9yr old). We all got better but she got worse. Bad cough that wouldn't go away and a stiff/painful neck. We went to the Dr and he checked her out. He told us to wait a little longer because it may pass. After a few days that pain subsided and her feet began to tingle, like they had fallen asleep. By the following day her fingers felt the same. By that evening her feet and hands were numb. The following day I came home early from work because she was having difficulty walking. I took her to the Doctor (she was unable to walk) who contacted the nearest hospital emergency room. They trasported her to the hospital and drew blood, did a brain scan and a mucus swab (stuck swabs up her nose to test for flu if I remember correctly). They were concerned about a nerve disorder that can occur after a flu. They tested for other disorders and between the original doctor and the hospital took 9 viles to perform tests. Everything came back clean! Her blood pressure is excellent, pulse excellent, no diabetes, no allergies, nothing. However, she's gotten worse! We stayed over night while they gave her fluids but the pain and numbness only got worse. I took her home and don't know if she's worse or if she's fatigued from all she's been through. They want her to go to a nureologist but EVERYTHING I see seems to point to lyme disease!

Here's the kicker. We don't have health insurance. What can I do? The visit we just had will wreck me. I'm beside myself. I'm watching my wife wilt away, we can't cover the bills and there needs to be a diagnosis. Sorry, I'm digressing. Please help me.
