Not on any other medications. The doctor has me on 10mg if prednisone. 1 tablet twice a day for weird bumps on the back of my tongue and a red throat because he can't find anything wrong with me. So I'm on these pills for 4 days.

Recently my legs and lower back have began to hurt and I read online that these side effects are serious. I'm worried because I can't get to anywhere right now as is 10pm and I have to take another pill soon. I read you shouldn't miss a dose of this.

Is this really urgent? So for this is the only side effect I have noticed but my legs and lower back sure do hurt maybe on a scale of 2-3, so not terribly bad. Why is this considered serious? I read it has to do with low potassium so I'm drinking Gatorade.

What do I do?
