my wife has a toenail which is known to have a fungal problem. She was on Lamisil to cure it though the treatments did not work; this was a few months ago. This evening she was trimming her nails and when she cut the nail smelly pus and blood came out. I am wondering if this is something we should go to emergency for or if this is something that we can wait to see a primary care doctor or if this is something that can be treated at home? any advise would help.
