hi,
thank you for providing the brief history of you.
As mentioned you still have pain,
tingling and
numbness in the thigh which is troubling you, also further you have a
spinal stenosis and disc degeneration, it is sad to hear you had it as a very early age.
a thoroguh neuromuscular assessment is advised.
Also, in your case what I feel is the weakness of the muscles which are not able to stabilize the spine. You need a thorough and deep assessment of the muscles of the spine as by which how to handle your case will assist us further. Also, may be your hip muscles will be weaker as, the hip muscles act as a base of support to the spinal column the strength in the hip muscles is of due importance. Also, stabilizing the spine with cores stability is of due importance. Also to understand that only spinal muscles strengthening is not the concern here, here the concern is to see the body as one
unit and rehabilitate as a whole. Also, the Strengthening of the
pelvic floor , hip muscles, core muscles , lower limb muscles and on later stages the spinal muscles will surely make the body as one unit.
I have seen cases of lumbar disc degenerative disease when patient was 16 years old. but applying the correct exercise prescription helped him back to action without aches and pain.
I will recommend you to undergo a proper assessment and then a physcial therapy as working out behind you will be a tough task but not an impossible one. Slow and steady wins the race.
I hope to see you recover soon.
