Do you think i have tinnitus?

I'm 15 and My hearing in my right ear has always been sort of muffled, for as long as I remember. But I just thought it was because my hearing was better in my other ear. But about 4 months ago I could hear a roaring sound in my ear but thought nothing of it. I could especialy hear it when I laid down. But about a month after it started, I could hear a ringing in my ear. I tried to ignore it, thinking it would just go away by itself but it still hasnt now. i researched tinnitus but thought the only cause was listening to loud music, but I found out yesterday that there is many causes. 1 Thing that I can think of that could have caused it is that when I was about 10 or something, I used to use my DS Stylus and put it down my right ear to clean it because my family didnt have any buds and they were always quite dirty. But wouldnt the ringing have started earlier? and also, i can only really hear the ringing at night or in the morning. Even if I cover my ears I cant hear it during the day, which makes me wonder... But at night I can still hear it if I cover my ears. I'd love you help! Thanks x
