Most times the ringing in the ears will go away on it's own in a few more days.
But you can try a few home care remedies for ringing in the ears.
Try Skull Thumping.
Cover your ears with your palms. Your fingers should be pointed back and resting on the back of your skull. Point your middle fingers toward each other at the very back of your skull.
Rest your index fingers on top of your middle fingers.
Using a snapping motion, flip your index fingers down off your middle fingers and onto the back of the skull. This motion will sound like the beating of drums. Because the fingers will also hit your skull, the noise may be quite loud. This is normal.
Continue snapping your fingers onto the back of your skull 40 to 50 times. After 40 or 50 times, see if the ringing has subsided.
Use Noise Suppression Tactics.
Several different noise-suppression tactics are used by doctors to mask the sound of ringing in your ears. These tactics include the following devices and techniques.
Make use of white noise machines.
White noise machines that produce "background" sounds, such as rain falling or wind whooshing, may help drown out the ringing in your ears.
Fans, humidifiers, dehumidifiers and air conditioners also serve as effective white noise machines.
Make use of masking devices. Masking devices are fitted over ears and produce a continuous wave of white noise to mask the chronic ringing.
Other than trying these above tactics I don't know what else you can do but just give it time.
I know how annoying ringing in the ears can be. It's pure torture.
