As others have noted, noise damage is irreversible and cumulative. So if you do damage to your inner ear now, it may not show up in hearing measurements for several years.
However, noise damage rarely causes physical pain unless it is a significant acoustic trauma. @everephebe asked which part of your ear hurts, and included a link to a diagram of the ear. As @GladysMensch noted, we can not diagnose you over the internet; but I might be able to narrow down the possibilities if you can be very descriptive of your symptoms and experiences. The same is true when you do see a health care professional in person – the case history is the most important diagnostic tool.
So if your problem persists, make an appointment for an Audiological evaluation to have a comprehensive hearing evaluation, and take a few mounts to jot down as many facts about your symptoms as you can (such as: when did you first begin experiencing them? Have they stayed the same, or worsened, or resolved a bit over time? Is there anything that seems to make it worse or better? Since around the onset of your symptoms, have there been ay other symptoms – even seemingly unrelated?).
