I've taken 2 paracetamols yesterday but my headaches was not gone, I slept for almost an hour and woke up to an excruciating pain thta I had to take mefenamic acid to go to sleep. Today, I did not have sunglasses on while taking my daughter to school and teh headache came back. I took advil, an ibuprofen and took a nap at my noon break but still aches.
