quote excerpted for brevity:
I don't recall the defense claiming the shoulder injury was "bad"; a medical patch, which can be bought at any chain drugstore, is not indication of anything serious. It could be a minor strain that a world class athlete wants to avoid straining further. In the wake of the horrible events of that night, I can see someone of OP's strength, even with a very bad shoulder, with the adrenaline pumping, able to carry her downstairs and all that.
Well in the USA, a medical patch is defintely a prescription item--as it contains prescription medicine. Can only be put on by a licensed practitioner. I do not know if that is different in SA. I presume medical records will be brought in.
