I went to the doctor week before last with cold symptoms - sore throat mainly, though with a bit of a fuzzy head that always comes before I get a cold. He diagnosed the beginnings of a URI, however, he wanted to examine me too. After checking my lungs and heart with a stethoscope, he got me to lie down, prodded my tummy to see if I had any pain, asked if I had any burning sensations when urinating and then asked if my feet sometimes get swollen.

I don't have any pain when peeing, it didn't hurt while he was prodding me, but my feet (and hands) do sometimes get swollen - I just put that down to the fact that it's really hot here at the minute (between 45-50C at midday), because I very rarely, if ever, get any swelling in the winter.

Just extra info: I am overweight (roughly 110-120kg and 5'4ish), and I'm currently drinking around 2 liters of water a day if not more. I had drunk 3 liters the day before going to see the doc.

I'm just very confused as to what he might have been insinuating I have, as to me, a sore throat, toilet problems and swollen extremities really don't have anything to do with each other... Can anyone please shed some light on the situation?

He perscribed me with Cataflam, cough syrup (even though I had no cough), antibiotics and something else, though I can't remember what it was...
