It sounds like you are experiencing mild symptoms that could be related to a common cold or mild sinus congestion. Since you have a headache and a blocked nose but no fever, this often suggests a viral upper respiratory issue rather than a bacterial infection.

• You may consider using an over-the-counter pain reliever like Crocin Pain Relief Tablet, which contains paracetamol and caffeine, to help ease your headache.
• Using saline nasal sprays or steam inhalation can help relieve nasal congestion.
• Make sure to rest and stay hydrated.

If your symptoms worsen, such as developing a fever, severe headache, facial pain, or if the blocked nose persists beyond 10 days, it would be important to see an ear, nose, and throat (ENT) specialist for further evaluation. If you experience difficulty breathing or severe symptoms, seek emergency care immediately.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
