Hello dear, Given the case history of sinus headaches, the symptoms as mentioned in your post can be attributed to exacerbation of Sinusitis. Tylenol being an analgesic agent, will only provide temporary relief from pain. Definitive management will involve a course of antibiotics+anti histamine preparations. Moreover, other causes for headache also need to be considered, such as: 1. Migraine 2. Cluster headache 3. Tension headache 4. Underlying systemic cause like Hypertension, etc. So, kindly consult your Physician & get a proper clinical examination done. Investigations like estimation of blood pressure levels, complete blood count & X ray of para nasal sinus will be helpful. Wishing you a good health. Take care.
