On Sunday October 26 I was in an ATV accident and received a rather deep puncture wound on the front of my left shin. I was taken to the emergency room and received a good cleaning along with 2 stitches, X-rays revealed there were no objects or debris left inside the wound and my leg was not broken but had hyperextended during the crash. I visited an Orthopedic surgeon Wednesday the 29th of October where I was prescribed antibiotics but wasn't given a promise that it would prevent infection. I am in so much agony and pain as of right now, not only has the pain gotten worse but it is traveling up from my shin to my knee cap as well. I am almost 100% certain my puncture has gotten infected, I keep it clean and wrapped with gauze but it stays swollen and hot to the touch. I have become nauseous and lost my appetite these past 2 days and have noticed a bruise on the heel of my left foot which seems to grow increasingly. I did not notice the bruise until yesterday and it was dime size, now it is the size of a half dollar coin and is very purple. I am concerned I may have an infection in my bone as well because of the excruciating pain inside of my shin and knee cap now. I will call my Orthopedic Surgeon on Monday morning to schedule an appointment. What are the chances it may be developing into gangrene? Should I go ahead to the emergency room or can I wait? All other areas of my body that were injured have healed beautifully except for my left shin. Thank you so much for your time!
