Brief Answer:
Tylenol will be the safe and best option...

Detailed Answer:
Hi,

The causes of headache are varied. I had a professor during my medical school training who opined that finding the exact cause of headache was itself a headache for most doctors.

Coming back to your question, yes typhoid infection can cause serious headache. In fact, headache is usually a common associated symptom / prodrome of all infections. That being said, from what I see in the above post, the numbers seem to represent sequential widal titres. And as the numbers are gradually declining you seem to be on the road to recovery. Hence I am not overtly concerned.

So if you have a serious headache now, you can try tylenol pain relief or any other brands of paracetamol which is locally available in your state.

Hope this helped. Let me know if you need clarifications.

Regards
