That HelenBeech knows her stuff! If you doctor will send you for Physical Therapy to a place with a pool, they can teach you all kinds of exercises that are helpful.
The pool is my favorite place to exercise. All of my parts work in the pool!

My doctor told me that weight bearing exercises are best. Walking is very good. Resistance exercises with very little weight until you work up to a little bit more. You shouldn't be in pain afterward. Watch your weight too.

that's okay keep on keeping on. life is sad but that is how we can help others going through same.

Yes hydrotherapy at least once a week really helps with mobility and pain reduction!

Yes pool exercises excellent!
Walking in the pool bringing knees up high each step taken.
Walking forwards and backwards heel to toe (like on a tightrope!)
Walking sideways.
Walking sideways with occasional squats
Walking sideways squatting all the time
That’s a few to start you off!
