Hello, I am a 60 year old male who takes a mild high blood pressure medication. Recently, I had a cold sore for the first time in 30 years. Upon clearing up last week, I began to experience occasional sharp, stabbing pains in the right temple area. My skin on my right forehead and cheek also began to feel sensitive and prickly. I experience this pain now twenty five to thirty times per day and it only lasts 3 to 4 seconds and only on the right side of the head by the temple but the skin also becomes sensitive near the pain area. Your advice.
