@tennis123 Physical therapists can do a lot of good, but you have to commit to following through to correct the bad habits. Bad posture puts extra pressure on the spine and with aging, the discs in the spine tend to dry out and sometimes weaken. The spine can grow extra bone when there is uneven pressure which can form bone spurs and bad slouching posture will put uneven pressure on a disc. I had a whiplash injury that eventually lead to spine surgery, so I try to be good about posture to keep my spine healthy. We can't stop aging, but the choices we make do affect how well our bodies function.

You are experiencing some pressure on nerves. I think a physical therapist can help and teach you good habits and best ways to strengthen to prevent this type of problem.
