if it were me - I would put that knee as my highest priority
because whatever you do ----------- you do NOT want to be heading off to hospital ---------- if you are out in the boondocks ------- and, you can get some imaging done by going to a surgery - and, perhaps being looked at in the carpark and getting a ref. for imagining - that might be ok
the risk then of course is at the imagining place? -- what are the odds?
then, if you got that done - you would at least know what's what -
if it required an op???????????????????????? well - that's really upping the risk ++++++
in the end - the knee isn't going to kill you
sorry -- glad that's not my problem --------- good luck with it
