Went for drinks after work with colleagues wearing high heels, where the heel of my shoe got caught on a bag strap on the floor and I fell and properly twisted my ankle. The heels have an ankle strap which led to my foot twisting awkwardly, fully outstretched back on itself. The pain was indescribable. There was an audible click and my ankle is swollen. I can’t really bear weight on it, plus don’t have painkillers at home. I did take a bath which helped but any advice?
