After considering how good my metabolism is, how healthy my diet is (especially compared with others), how much exercise I have been getting until recently (due to an unidentified hip problem - UHP), I have concluded that I am most likely intolerant to something.
There is also the possibility that I have Oedema. Corticosteroids may cause Oedema and after all I do take two types of inhaler multiple times a day.
Anyway, I'm going to be cutting out salt, which may cause water retention. Salt isn't a very difficult thing to cut out so I'll also be going dairy free for a while.
