I had several bouts, but this last time I had it, I could shake it. Required exercises didn't work and the doctor said to wait it out. So I went to physical therapy after dealing with it for about 2 months. I was amazed as to how this helped. It did take a few visits, but each time it got better and I haven't had anything for 4 to 5 months. Good luck because I know it's not fun or easy to deal with.
