Severe Genital Herpes outbreak. What should I do?

I went to the E.R. yesterday thinking I had an abscess on my penis and was diagnosed with genital herpes. Last night my penis was slightly swollen and mildly hurt. When I got home the pain ramped up and today at work every step I took was torture. He prescribed an anti-viral and a cream for the pain and sores. I could not get the cream because even with insurance it was $600. So here is my concern my penis is not big and I was circumcised poorly as a baby so my foreskin has swollen around the head of my penis. I have to pee sitting down and can't pull my foreskin back so I am having to pee through my foreskin and some of the pee stays behind in the swollen crevice where the sores are and seeps out slowly. I was told that 99% of urine is sterile and that the first outbreak is always the worst. So finally here are my questions......with swelling this bad should I go back to the ER? (I have to wait 30 more days for my insurance to kick in at work til I can see a doctor) Will me peeing through the foreskin cause infection? Is there anything I can do to reduce the swelling? Anything to reduce the pain? Would Tramadol help with the pain? Please someone help me. My wife is very supportive and the ER doctor seems to think that I did not pick this up through sexual contact but coming into contact with someone who had herpes and touched them selves and I touched what they touched ans so forth due to the fact I've been faithful to my wife for 7 years and she is negative. Please any advice will help.
