answer:Try an elastic ankle support and bring a cane and some ibuprofen, if you are determined to go. Have you been icing it? These are stop-gap measures; the conservative advice is to stay home and use the RICE treatment. Rest, ice, compression, and elevation (treatment endorsed by all mommies.) It took three months for that ankle to feel normal again, and I hated it. Are you prepared for another three months? Is one evening of musical pleasure worth it?
