I have been having little tiny head spasms on the top of my head lately. At first, it was once or twice a day and felt like maybe a bug was on my head. Now it is 10-12 times an hour. It is just a small nuisance, but am worried about it increasing. When I am on the treadmill, it seems much more regular and will go away a few hours after and not start again until I start the treadmill again. Anyone else get this?
