Hello, Most probably it is due to peripheral vascular diseases where blood flow to the distal limbs get blocked and thus leads to symptoms like cramps and pain. However, we have to rule out other causes like peripheral neuropathy and varicose veins. As of now consult a general surgeon and plan for an arterial Doppler to make a diagnosis. You can take analgesics like tramadol for pain relief. Make sure that your blood sugar level is under control and avoid stopping because uncontrolled diabetes and smoking worsen the symptoms. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Shinas Hussain, General & Family Physician
