No they are usually a reaction to a stressed out or lowered immune system. They can also occur after being out in the sun or very cold weather for long periods of time.
About three weeks.
That totally depends on the reason you have it.

I had a allergic reaction to penicillin, i took 3 tablets of amoxicillin and the next day; my fingers swelled up and i had a rash. So about 12 to 24 hours, however, even if the drug that caused the allergic reaction has left your body, the rash and other symptoms can still stay.
Im not sure i never have but you might
When you feel well enough.
i took lexapro for about 6 months they had to keep increasing the dosage because it would work just for a little while i actually became allergic to the drug because of this. you should have done went thru all the symptoms of withdraw after a couple of weeks. talk to you dr.. as i said i ended up being allergic to it. because of the dosage changes and such. please talk to your dr. It took me about 3 weeks to stop feeling disoriented after I stopped lexapro
Not very long, I would say a day or two.
