### input:
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 wasnt 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!

Hello, It seems that you are uncertain about following.1)Whether there is any infection at puncture site?2)Bruise gone unnoticed3)Whether there is any chance to develop gangrene?4)Have to wait and watch? Answers are here.first u have not mentioned that whether u have been prescribed any painkillers or not. Neither you have mentioned the name of antibiotic. Now,1) If u have developed any infection at your wound site, u probably have developed fever, which u have not mentioned .2)Bruise is called "delayed bruise" as it develops after about certain time of actual impact. If it is of purple color, it's in the phase of healing. No treatment required for that except painkillers.3)There is a chance to develop gangrene, when you leave your wound in unhygienic condition, do not take proper antibiotics, already have undiagnosed diabetes. Otherwise, there is negligible chance.4)If pain is unbearable there is no choice for wait and watch. Anyway if you have consulted an or tho. Surgeon, He must have given you painkillers, if surely not you should consult him. I am not suggesting you any painkiller online, because I do not know your gastric history. Get well soon.
