All one sided headache problem folks, please check out Cluster Headaches. They are called “clusters” because they come one after another usually. More severe than migraines if you can believe that. Always involve only the same side of head. Teeth, ear, jaw, all will be in hard pain. The cure is O2, yes Oxygen. At first sign of one start breathing deep and long breaths pulling air thru your nose, exhale thru mouth.. Do so until pains subsides. If this fails see you doctor and get RX for E-tanks of oxygen. Set flow meter to 8 to 10 (a lot). Clusters are the worst headache imaginable. And so simple to eliminate. Best to all. And get those shoulders out of your Ears and try relaxing some! Treetop
