Yeah, I guess you could say I've had my ears ring for "3 days or more". They've been ringing for 40 years now and counting.........,but who's counting? :?
Use ear protection anytime that you have the choice. Unfortunately, I didn't have a choice.
Also use eye protection, not only when you shoot, but when you do almost anything....... driving nails, cutting wood, reloading, etc. ANY kind of safety glasses will do the job...... even the $4 glasses at Wal Mart will protect your eyes. Buy a dozen pair of the cheap glasses and put a pair everywhere..... in the car, garage, workshop, shooting bag, etc. That way, you will always have a pair available when you need them. However, you must put them on to do you any good. They don't protect anything sitting in the case.
Also buy about 100 pair of foam earplugs. Keep several pair everywhere. That way, you'll always have them available when you need them. You'll also have some extra for your friends who forgot to bring theirs.
Even though your ears are ringing now, it CAN get WORSE. So don't fail to use hearing protection in the future. Protect what hearing you have left.
