Can Masturbation get rid of stress?

I get Migraines and i got oe today. I think it was a result of stress because i am in the middle of my GCSE's. At first i didn't think it was stress because i never feel stressed over stressful things, well i don't notice it on the outside. I think a lot of my stress is built up inside my body hence the migraine. I heard masturbation gets rid of a lot of stress and tension and i was just wandering if that is true??
