Could it be a side effect of one or combination of medicines? My current antibiotic has "headache" as one (among many others). Check online or your pharmacist. Possibly high blood pressure?? In the off chance that it could be serious, you might want to check with your doctor, right away. May you feel better soon. May blessings abound. B
The pulsing/throbbing seems like it is now in my neck and even my left leg and foot. I really only notice when I am laying in bed. Not getting any better. Maybe it’s nothing.
