I cut my finger a few days ago on some stainless steel. Went to ER, received stitches; My finger was x-rayed, cleaned, stitched, and bandaged very tightly. It is now swollen, blistered, red and painful. Could it be infected or it is just the affects of being tightly bandaged. I have been cleaning it and applying neosporin and also keep it covered everyday. Should I change my method of treatment. Should I burst the blisters.
