Welcome to NT!

I agree with Snoopy, especially since all of this started after your injury 3 years ago. While it doesn't mean that you don't have MS or anything else going on, I would try to get to the bottom of the damage that the slipped disc at L5 caused. Many people experience issues long after they slipped a disc. For some, it is a life time. I know that is not something you want to hear but getting a right dx is so important as there are things that can be done to help you - physical therapy (which I know several people who went this route instead of surgery and did extremely well), pain medications/injections, etc. Going to a good neurologist as well as orthopedist is a good place to start.

In the interim, those of us with MS can certainly relate to your symptoms and we each experience some or all of what you are experiencing. Please know that we are here to help you through this. Hang in there and let us know how you are doing.
