My friend, i think you need to see someone. I am afraid that if i tell you to walk and you aren't ready (which most people are) then that will not help. But if i tell you to rest and you need to walk, that won't help either.

If you can see a local physio, that would be the best.

It sounds like you need peace of mind...

...i can't safely give that to you except to say that most people don't have an issue and just need to develop confidence, strength and endurance.
