Painful joints and swollen feet? Any idea what it is?

[Waffling]

My knees, hips, buttocks and back are terribly painful when I move. My ankles and feet have really swollen up, the skin feels too tight.

It's been three days now.

I took Difene 75g on day 1, but then my ankles swelled up so I'm scared to take it again.

Any ideas, I'm hoping it'll just clear up before I have to face the doctor.

You need to go to the doctor, have you had a virus or anything recently?
Also do you have any pain in the upper half of your body?

Nothing in upper half. No virus. Thanks.
