sometimes coming off a medication especially a psychoactive like an antidepressant can cause odd side effects like that. it has to do with the brain readjusting to not having the medication but it isn't usually harmful. you might want to mention this to your doctor if it become really bothersome.
what causes pulsating sounds in a person's head? . i am on a high blood pressure med and take it daily. but recently after going off an anti-depressant i have these weird pulsating sounds in my head that almost resemble a heart beat. it's not constant just weird. any ideas?
