Burning butt!

I'm wondering if I have hemroids.  I feel my anus a bit swollen and it burns when I poop.  The burning goes away after I'm done.  I had some strenuous doggy sex a few days ago that made me anus sore, but not anal sex.  I did start to get a yeast infection the day after that crazy romp and I'm on treatment for it now. I thought it could be yeast irritating my bum. I don't know...
