Hi Thanks for posting your query on HCM I have read and understood your concern. With a past history of diabetes and peripheral neuropathy, the symptoms you describe are typical of a diabetic neuropathy.Poor nervous transmission and poor circulation are all common with your condition especially if your blood sugar is not under control.I will advise you try the following: -Have you blood sugar under control -Continue with gabapentin which is a good pain drug well indicated in peripheral and diabetic neuropathies -Have you diet under control and take enough vegetables -You may take some B complex vitamins -Take enough water -Avoid putting on tight shoes I will also advise you see an Endocrinilogist or a Neurologist for examination and better follow-up Hope my contribution will help you Wish you good health.You may write back if you got more concerns. Regards Dr Mbuomboh
