I have exactly the same experience. It began in my early thirties during a few stressful months. It stayed for about a year but then it was slowly getting better and was gone a few month later. All cures seemed like snail oil to me, or like placebos for people who can't handle the thought that they can't do much about it. So I simply accepted it, knowing that it will either go away on it own or it won't. My partner was actually more stressed over it than me.
