Can Bactrim Be Taken Along With Amoxicillin For The Lump On The Clitoris?

I have had MRSA on my vulva before a couple of years ago and it was treated. I got a raised bump above my clitoris and it just got larger within few months but with no head. Eventually it hurt and I squeezed it and it ruptured. Went to DR and culture came back as Strep? I thought it would be MRSA again. could it be both because amoxicillin not curing. Can I take Bactrim also?
