Afternoo, I m currently diagnosed with Spinal Stenosis, and have been for some time now. Lately, I ve been experiencing a severe pulsating pain on the left side of my head above the ear area. I ve had it for about 3 days now. It comes and goes, I don t experience any dizziness or nausea, it just hurts! I use to get that pain all over my head (cluster headaches), but now it s just in this one place. Any suggestions? Thank you Ronald Thomas
