(Concern) Headache

My father has been having trouble eating properly during the summer and his headaches have worsened, so I am worried.

Since you farm, there's more work to do in the summer.

Because it's hot, you haven't been able to work well or eat properly, so you've lost a lot of weight. They say that taking Tylenol when you have a headache helps you feel better. Still, I was worried, so I had an MRI scan done, but they said there are no significant issues.

Recently, I'm worried whether my headache is caused by high cholesterol levels or if it's psychological.
