[/INST] Hello,This can be a Peripheral Arterial Disease.Please have  your foot pulses examined by a doctor.If your foot  pulses are absent, then you should see an Interventional Radiologist like me for an Angiogram and look for any blocks in the foot arteries. These can be opened at the same sitting by an angioplasty.Regards,Dr.Saurabh Joshi,MD, FNVIRVascular Interventional Radiologist </s>
