Hey Harvey!
Well, without a clinical evaluation it would be difficult to determine the cause of your symptoms. Possibilities that may need to be considered include neuro-muscular causes such as, injuries, dislocations, micronutrient deficiencies etc. I would suggest getting this evaluated by an orthopedician for an accurate diagnosis and appropriate management.
Hope this is helpful.
Take care!
