i was bitten by my dog in june., the bite went thru my flexor tendon on my right hand. i had surgery to clean out the infection. now after 7 weeks, i am still having trouble with my hand,my knuckles are bigger but don t seem to be swollen, they seem to have just gotten bigger. i cannot straighen my fingers anymore and am wondering if this event, getting bitten and having the infection could cause me to have arthritis in my hand/fingers now?
