My neck muscles are too tight after chin reduction surgery. Can a revision help loosen the muscles?

In the spring i had chin reduction surgery. I wasn't aware that it would involve tightening the muscles under the chin so much. Currently the muscles are so tight i'm unable to hold my head up properly and spend most of my time laying down up to 16 hours a day. I'm unable to work and leave my house and i'm very scared. I went to see a doctor and he said there was nothing he could do. Can a revision help loosen the muscles? I'm very worried that i've ruined my life
