Hi Kathy! Yes, I have this and I suggest that you bring this to your drs attention as this could be another symptom that something is wrong.
Have you had any tests to determine the source of the problem?
You may need a cane temporarily and some physical therapy to help you use the cane correctly and to help strengthen any muscle groups.
Good luck and I pray that you find your balance improving and pain lessoning each day.
Hugs, Pep
