I mildly rolled my ankle getting off the toilet Wednesday morning and I’m just now putting my full weight on it (old people problems amirite?). You sound like an immediate hospital visit bro.
Unrelated your s/o could stand to have more patience for you, unless you being a jackass resulted in your injury. Otherwise it might be time to evaluate your relationship. How someone treats you while your sick, injured or incapacitated in any other form, gives great insight into the quality of your bond.
