D. Sinusitis

A. Rebound symptoms.

Explanation:

This case or scenario called rebound symptoms can be said to be a syndrome which is especially common or peculiar to people whose medication has caffeine, which is often included in many pain relievers to speed up the action of the other ingredients. Though caffeine can be helpful in medications, along with the other sources you get (coffee, tea, soda, or chocolate), makes you more likely to have a rebound headache.

When a pain reliever you take wears off, your body may have a withdrawal reaction and the pain may come back. This prompts you to take more medicine, which only leads to another headache. And so the cycle continues until you start to have daily headaches with more severe pain more often.
