It's very hard to comment on your condition since you do not have any medical history of diagnostics to help rule out serious concerns.

As has been suggested on another thread, it sounds like a neck issue. Becoming ambulatory may start an inflammation in your neck that causes some neurological dysfunction.

Some of your symptoms possibly warrant a visit to the Emergency Room. But you should not drive yourself.

Have you looked into whether your state has a Victim's Assistance program? Some states do and it is for a situation similar to yours.

I have a hard time relating to your 'no insurance' situation since I have always covered my family with at least some basic health care plan, even when we were living on a below poverty level income for about 7 years. Being self-employed, I always paid for our health plan out of pocket. Our health plan was paid before we paid the rent. A PPO plan with a high deductible but also wellness care is a minimal necessity for a young family.
