DH's left ankle started to hurt and swell for no apparent reason 2 weeks ago. The following day his right knee also became painful and swollen.
We were going away on holiday for a week so I pushed him up to the doctors (not literally). She didn't offer a diagnosis, but said it might be an injury - this doesn't seem likely with it involving both legs. She has arranged some blood tests, but due to our hols these aren't happening until mid-week.
It has not improved during or after our holiday (he is icing them and keeping his legs up as much as possible).
Today his left foot has swollen to twice the normal size. He says that the arch of the foot is incredibly painful and he is now having real difficulty walking.
Any ideas? I have persuaded him to go back to the doctors, but I would like to have some idea of what might be going on. Googling "swollen legs" is just too vague.
