<s>[INST] I stub my big toe on a concrete stair on Sunday. It turned red a little and had a bit of swelling on top near cuticle. Today it started leaking a dark yellow liquid and then redish. The nail looks like its detaching but it hurts to walk or put pressure on it. I am freaking out. What can I do? What will happen? [/INST] HI, thanks for using Chat Doctor Trauma to the toes can cause the toenail to eventually come off completely, but it would regrow. It may be best to visit your doctor who may be able to remove the toenail completely and therefore speed up the healing process. If this is not an option, then you can continue treatment at home. This would involve the use of an anti-inflammatory painkiller to reduce your discomfort and applying antiseptic cleaning solutions to the toe to prevent infection. Examples of painkillers are aspirin, naproxen, Catalan, ibuprofen. One of these should be able to help you. Available over the counter. I hope this helps </s>
