Im 22 yrs old and a few days ago i noticed that my left ear makes this static/crackle noise. it does it when things get loud or high pitched..like if someone is typing on a keyboard, talking loud, water running, cars going by, etc. its not constant. it only does it when the noise comes then stops. the crackling noise isnt loud but soft. i dunno what is wrong with my car

. its never done this before. im thinking i messedup my ear from listening to loud music. i covered up my right ear and i can hear clearly out of my left ear. doesnt seem like theres any hearing loss in the left ear at all.
im going to go to the health center to get it checkedout. i hope to god its not tinnitus.
