I cut my thumb knuckle on an aluminum can last week. There was a lot of blood but then it healed quickly with not problems. Now there appears to be a lump underneath and the cut is gray in color and it hurts to bend my thumb. Is it possible it became infected? I had a tetanus shot in 2004. Thank you!
Hello, Welcome to Chat Doctor, As you cut your thumb knuckle with an aluminum can last week which was followed by lot of blood, and it healed quickly without any problems. As there is a lump underneath the cut which is gray, and it hurts when you try to bend your thumb and this may be due to underlying bleeding which has lead to your problem. I would suggest you to follow 1. Bending the thumb in the hot water2. Tab Later D, Twice daily for 5 days.3. A course of antibiotic like Tab Augmenting, twice daily for 5 days. You can take these medicines by consulting your doctor. Thank you.
