Speak to a physical therapist when you have a problem
I have been going into the gym and weightlifting and doing specific stretching exercises daily for 4 years except when out of town or sick. Still, I had trouble walking.
I went to a physical therapist who happened to have a phd and was also a Pilates instructor. She tested all of my movements.
It turned out that I have lost elasticity (over 65 years old). She gave me three exercises to do three times a day plus riding an exercycle. Have followed the instructions for the last month and added additional reps. What a difference!
Don't hesitate to seek professional advice.
