@sklaing The body's a complex machine with a lot of "moving parts" and in my case pretty much all of them malfunction in at least some small way, so I've always been a doctors favourite patient or their most hated, depending on how much they like their job, heh.
BTW, I haven't forgotten about the promise to look into the immigration stuff for you, I have to go in next week for the monthly stuff about the physio coverage for the leg so I'll take a look then if I don't get down before then!
