No, it does not get worse with exercise. I started muscle therapy just after posting this. I do the therapy now at home and after 11 months I find I am able to go up and down stairs a little better and my balance seems to be better also. I have been diligent about doing the therapy 3 times a week. My regiment is as follows:
1. Chair Squats - 3 x 8
2. Leg Extension - 3 x 10 (30#)
3. Straight leg raises - 3 x 20
4. Stair step-up/downs - 3 x 8 with my left and 3 x 8 with my right.
Thanks for your concerns.
