I've been fortunate so far to not have much pain from these back issues but the last few days, my left leg has tingled from time to time. It doesn't really hurt, but it does worry me a little. I have a numb spot on my leg already. Could this escalate to losing feeling in my leg?
Actually speak to your doctor because it can cause numbness and tingling because your nerve can get pinched with the back issues.
No, I doubt it very much, I've had these feelings all my adult life. I think you should talk to your GP as you might have something else going on, which might need manipulation.
