Healing Tinnitus

This past weekend, on Saturday afternoon, I shot a shotgun shell from a rifle. I had shot a few rounds of a 22 at first, being much weaker and not requiring plugs. I don’t know anything about shooting, my friends do, and they were trying to teach me for the first time, but forgot to mention the necessity for ear protection with a higher caliber rifle when they had me try it, and I, being rather stupid at the time, aside from totally unaware of how to shoot or how loud shooting can be, shot without any ear protection. I’m right handed, and so when I shot the rifle I didn’t really have any problem with my right ear (at all), but immediately after firing my left ear went deaf for a few seconds, accompanied by a loud ringing tone. My hearing came back gradually over about one minute but ringing persisted for about two minutes after the shot, and then the ringing came to a complete stop. However, there was a feeling of pressure and fullness in the ear. Although today, Monday night, this feeling of pressure has slightly begun to go away, it is still there, and I’m getting worried. I don’t really think it’s tinnitus because I don’t have any ringing in the ear. In fact the ringing only lasted about one or two minutes before going away completely. I was told that I probably did lose some of my high frequency hearing but that it probably won’t be that bad or noticeable (by the said friends). As of right now my main complaint isn’t that it’s hard to hear out of my left ear, as I can barely distinguish the difference in my ability to hear between my left ear and my right ear. However, my left ear and my right ear FEEL completely different. The left feels as though it’s under pressure, at times full of wax even though it’s not, and generally just not as open as my other ear (like the two ears are out of balance). Also, if I touch the area of my face beneath my ear (behind my jaw and underneath the ear itself), it feels different than if I touch it on the other side, like it’s slightly numb. Visually it does not appear to be swollen; if it is then it’s barely visible. I have tried using cutips to see if I can get at any wax, and I have, but it appears of normal color. I read somewhere that if it’s clear that can be a sign of actual damage. Even after getting the wax out, though, it hasn’t helped much with the feeling of pressure and out of balanceness. I know that the ringing is probably something that would never go away (thankfully that hasn’t occurred at all so far, after the shot), as I’ve read has happened with other people in similar situations (online), but I’m more concerned with my symptoms of pressure and fullness of the ear.
I don’t know what to do at this point. I’m really hoping that in a couple days the pressure will be gone and that my head will at least feel balanced, even if I have suffered some minor hearing loss, which is unfortunately a given I’d imagine, but I don’t know if that’s realistic. Most people complain of ringing in their ears, it seems, after this type of situation, but I have different symptoms.
Has anyone had personal experience with this or have any advice to give?
