Thanks for your query.
* The problems are not due to any medicines, including Insulin
: they can, however, be due to diabetic neuropathy- an inevitable complication of diabetes
which affects the nerves, particularly those of the lower limbs
* Further, there is a strong possibility of other causes such as, prolapse of a disc (the "cushion/washer" between the vertebrae) or, collapse of a vertebra of the lower back, causing compression over the nerves of the lower limbs.
* I therefore strongly feel that you require an MRI
of the lower (LUMBAR) spine. Keep your blood sugar under tight control.
Consult your treating doctor/orthopedic surgeon and discuss the problems with him. He knows what is to be done further.
Hope I have answered your query.
