Your symptoms suggest a menstrual-related migraine (hormonal headache), which commonly occurs 1-2 days before or after periods due to hormonal changes. It can cause severe headache, nausea, and body aches, and may not always respond to medicines like Diclofenac sodium. You can try resting in a dark, quiet room, staying well hydrated, and using simple pain relief. If the headache is unusually severe, different from your usual pattern, or associated with vomiting, vision changes, or weakness, seek medical advice promptly.

Increasing ear pain that is not responding to tablets or local application may indicate an infection or inflammation inside the ear. You should avoid putting anything into your ear and consult a doctor or an ENT urgently for a proper examination and pain relief.
