The injury you had before may indeed cause some injury to some nerves and other structures in your buttocks and leg area that can be causing you this pain. Other possible causes includes work related injury (some nerves may be impinged upon prolonged seating) that may be related to the drum playing itself. The cramping may also be due to inadequate blood drainage of the lower legs which causes the accumulation of lactic acid. Possible work ups that I can think of would include an MRI (to rule out spinal nerve compressions) and vascular studies of the lower extremities (to analyze the blood vessels). I suggest that you discuss these options with your doctors, and I hope the cause can be found soon.
Regards and keep rocking.
Thank you for your time and valuable input.
