Hi Sharon - this happened to me a couple of years ago, so I know what you're going through! Try and go without socks/tights and wear open toed shoes (which should be easier as its summer- allegedly!) so that the nail bed can breathe and stay healthy. Moisturise the nail bed every night too, using cotton wool to rub it in if its still sore, as this will stop the nail bed hardening before the nail has a chance to grow back. It took about 9 months to grow back fully, but its perfectly normal now, so dont let anyone tell you they dont grow back, as people did to me!
