I 'll make an exception in not giving "medical" advice, since I kind been there, 'done that. I was exposed to many years of loud rock bands, some drag race cars, and some large military fire.
Your initial recovery is good, so you can relax on that. If it soon gets worse, to where you can't hear normal conversation, have pain, or your balance gets wobbly, get some help. For you, if attending a University with a med school, you may get it there. I expect there has been some permanent loss, in high frequencies (because that's the bandwidth that's common).
The assistance is basically going to be a thorough exam that won't hurt, followed by advice. Here's the advice: Don't do this again. Don't park yourself directly up front of a big act, big speaker, or big amp. If/when doing so anyway - or around race cars, guns, some power tools, etc. - wear hearing protection, at least like pro-grade rated ear plugs (cotton is useless). Don't remove one so your friend can yell in your ear, either.
Mother nature just gave you a little smack about the rules. Take the lesson, as they will add up to a net loss. Resistance is futile.
