I also have hypermobility and told by an EMG specialist that I should be assessed for hypermobile ehlers danlos syndrome by a rheumatologist.

Have you had an ultrasound of your ankle/calf/knee/thigh?

Have you ever had cortisone shots in your calf? Have you tried nerve pain patches like Salonpas lidocaine patches or nerve pain creams like capsaicin? Have you tried icing or using heat on your calf? Have you soaked in a warm epsom salt bath?
