Should I go to a music festival tomorrow? Please give me advice!!!?

Hey guys. For the past week I've had ringing in my ears, I'm not sure if it will be temporary or permanent. I shot a few rounds out of a handgun with no ear protection is how it happened. Tomorrow, there's an even at a local recreation park called "Mayday" which features instrumental bands, and Dubstep music. I'm not going to go if I have to wear earplugs, it just ruins the point of it all. It's either I'm going to go, or not at all. I do have an appointment coming up with an Audiologist/ENT to see what damage I may have caused (I'm sure years of blaring Slayer & tossing firecrackers around didn't help this either). It's sad that I'm only 20 & might have permanent Tinnitus forever. Anyways, I don't HAVE TO stand close to the speakers, and won't, but I'm just wondering if the loud event in general will furthur damage my hearing. Thanks everyone. I have been looking forward to this event for a very long time.
