Dr. said their is infection in my ankle joint, i have a problem in my left foot from last 8 days, it looks like their is no sense in my foot.. it started from toe and reached upto my knee within 8 days. i really worry about this... i am waiting for your  favourable reply... [/INST] Hello dear,Thank you for your contact to health care magic.I read and understand your concern. I am Dr Arun Tank answering your concern.If you are not feeling sense in the feet than it is the matter of concern.I suggest you to visit the ER immediately. Many a time infection causes anaerobic bacteria to grow on infection site which creates gas and further causes sensation impairment.Such changes can lead to gas gangrene and requires a amputation. So as if you visit the hospital immediately than you can prevent it from spreading upwards.I will be happy to answer your further concern on bit.ly/DrArun.Thank you,Dr Arun TankInfectious diseases specialist,HCM. </s>
