For as long as I can remember. It used to be very bad, but now it varies wildly in intensity, most often it's bearable.
When it gets especially bad, I try to do either of two things.
The first being using this
website, sometimes after using it, I find it to be a bit worse, though the temporary relief is mostly worth it.
The second being a set of instructions I found a while back. "Put your palms on your ears and thump the soft spot in the back of your head with your fingers, should resonate and feel like your head is the inside of a drum. 15-30 seconds." This ones either hit or miss for me.
