Hello..as a recently diagnosed Asthmatic I purchased a new vacuum and carpet fresh..approx 3 hours later while on the computer had a stabbing pain in the right side of my head approx between my temple and ear it radiated to my right hand. It only lasted maybe 3 seconds. No further isssues that night. The next day started having a headache on the right side from my eye to the back of my head skin was sensitive to the touch and appeared swollen around the initial pain site. In the afternoon took an anti-inflammatory and the pain subsided. Since then I have had very little pain but a "full feeling exist" on the right side as if my sinisus were clogged. I have not had any blurred vision or dizziness, no naseua or dialated pupils. I also have no history of headaches..I have not had one since middle school. Can you help..was this just a reaction to the carpet fresh that caused a nerve or inflammatory reaction..I llok forward to your response.
