Hi. Thanks for your query. If there is pain in spite of Gabapentin and Tramadol you are taking for leg pain, The cause of the pain in abdomen has to be searched on. There can be a mild infection due to diabetes or a chronic problem. I would suggest to go for a clinical examination for pain in abdomen and go for ultrasonography/ CT scan of abdomen to confirm or rule out specific infections. As also go for blood , urine and stool tests as there is a possibility of a complication due to diabetes.
