The reason you're not getting better with oral anti-fungal medications like Lamisil is that you don;t have a fungus. You have traumatic paronychia--inflammation around the nail from biting, picking, etc. You will get better if you leave the nails alone. Get the help you need--behavior modification, artificial nails to keep from being self-conscious while the nails grow in, which takes months--whatever it takes. Medication does not help this at all, so please stop the Sporanxo, and consult a skin doctor, who knows what fungal nails are, and aren't.
Best.
