What Causes Swelling And Redness On Foot Post Injury?
You need to wait and see.
Detailed Answer:
Hello!
Thank you for the query.
As the wound was not large, however quite deep, you are not able to see the whole injury. Pencil could reach the deeper parts of the foot including muscles and tendons. If so, the healing process will take some time. It does not seem infected.
The swelling you have is most likely caused by inflammation of deeper soft tissues. Usually such inflammation lasts like for few weeks. During that time there is nothing you can do about it except icing it and keeping the foot higher when lying down (like on the pillow). And try to not overload the foot.
If after few weeks, the swelling will be still present, please consult your doctor and have soft tissues ultrasound done. There is always a chance that a part of the pencil could be left in the tissues.
Hope this will help. Feel free to ask further questions.
Regards.
