i am a type II diabetic. I recently had a root canal. The perscriptions were cephalexin, hydrocodone/acetaminophen and Ibuprofen. Two months before that my Dr. changed some meds for my diabetes to NPH Humulin N. Last week I noticed for the first time in my adult life my legs and feet where swollen.. On Friday the swelling was gone. But alas on Sunday a new infection starts in my teeth so I took a Hydrocodone to sleep through the night until I could get to the dentist and monday morning my feet are slightly swollen. I think it may be cause from the Hydrocodone but I am not a Dr. and did not find it as a side effect.
