I have been diagnosed as having a degenerative disc with a pinched
nerve.  My right leg has become weak causing it to buckle. I have
fallen a few times.
I am doing physical therapy, mainly, exercises such as straight leg
raises, , knee -to-chest stretches,etc. for about 10 days.

I want to  add some strengthening exercises using 1 pound ankle
weights.  Will my right leg get back to normal- no weakness, no
buckling, no need to slowly step up or down?
How long does this rehabilitation usually take?

Thanks

Allan
