Hi Talia,
I am sorry to hear about your pain.
I agree with some of the other replies that you need to see a doctor, probably more than one. You may have more than one thing wrong. Several things can be damaged after a car accident.

I also had a car crash and it has left me with some of your symptoms but not others. I have some neural damage, to my brain and back. This is manifest in symptoms such as tingling, pain, and really bad headaches. However, I don't have any numbness. Perhaps you have a trapped nerve? I think that the tingling could be due to subtle neural damage, but nothing that would be visible on an MRI.

I also had an MRI and there was a prolapsed disc in my neck. However, some of those changes might have been there before the crash, due to aging or bad posture. I have had some physiotherapy on my upper back and this was helpful, but you need to find a manipulative physiotherapist who really knows what she is doing.

I didn't find that a TENS machine helped at all.

I also have post-concussion symptoms. (There is a forum on this site about that if you think that that might be part of your condition.) Have you considered that? Did you have any confusion, post-traumatic amnesia or where you knocked out?

You may have some trapped nerves in your spine leading to numbness but I think that your condition might be more complex. Do do see a doctor. A general family doctor will not be specialized enough. You need to see a neurologist who is familiar with so-called mild traumatic brain injuries and spinal injuries.

Good luck. I hope that you find someone. Do feel free to send an email if you want to compare our conditions more.

I hope that you return to this site and read some of the advice that people have posted.

All the best.
