They did not, I was told that the symptoms I have should subside within a month and if they don't to come back - but in the meantime to just use painkillers to manage, and try to eat as much as I can. It eventually started improving(although it took me a long time to recover to "normal") so I never went back. Looking back at it now I think it's because while I felt absolutely awful and it was rough from my point of view, for them it wasn't a severe enough case to start any more advanced treatment since all my blood tests were still "ok-ish" and I wasn't collapsing or anything. That's just my guess though.
