There are many creams available in the market which are to be applied carefully to the localized mole. Any idea of a good medicine or cream?

I mean light red.

I’m getting a mole on my upper arm removed on Thursday. I’m 16, a total wuss, and completely nervous. It is not a cosmetic operation; the dermatologist I went to immediately discussed removal as soon as he saw the mole, as a precaution.
I’ve already gotten sick to my stomach today and had to go home from school early. I also didn’t go Monday, because of the same feeling. I’m not going Thursday, obviously, and not Friday either, so that I don’t agitate the wound and can let it heal for a few days.
I have some questions:
1) Is the removal itself painful? I’m almost positive it will be an excision with a scalpel, then stitches.
2) Is there any reason to stay home tomorrow, as to not cause any unneeded stress to the area? Keep in mind, I get sore a lot from doing P.E. for an hour and a half, not to mention I carry a good-sized load of heavy texts.
3) What can I expect after the surgery? What kind of pain, discomfort?

I’d like answers as soon as possible. Thanks so much.
My mom and I decided to just keep me home from school tomorrow. Thanks for your answers; I don’t need any more. ♥
Actually, I don’t need any more answers about the school. I’d still like answers pertaining to the topic of pain and such.

Okay.
Thanks.♥

And anyone know what type of procedure is used for removing larger moles? Laser or scapel?

I have three moles on or near my chin and one on my forhead that are getting on my nerves because i either nick them when i shave, or people think they are zits, or they stare at them while talking to me. I have had enough of this ! LOL
How much will a doctor charge me to get rid of these four moles? They are not cancerous or anything. But they stick up a bit (not flat moles) and are a normal brownish color and are not that big, but they are noticeable.
