Are antibiotics ok?

I developed cellulitis and am going to call my doctor tomorrow. I need to get it lanced and I know I'll need antibiotics as I've had it before. Haven't needed any since surgery. Idk if my refused doc knows too much about what is ok with bypass. I'm thinking I'll get Bactrim. Is this ok to take with my new stomach? Thanks!

I just recovered from an episode of cellulitis. I was on antibiotics three times a day for 10 days without any problems. 

Reporting no problems after finishing antibiotics due to a bladder infection.  In fact, antibiotics are like a vacation from constipation.

Shoot, the constipation part is worth it right there! Lol

Thank you both so much!
