Pain in the upper right jaw that started with gum swelling and now hurts mainly while chewing is most likely due to a tooth-related problem such as a gum infection around the last tooth, food impaction, early tooth decay, or irritation from a partially erupted wisdom tooth; even if the swelling has reduced, the underlying issue may still be present. At this stage, you should maintain good oral hygiene by gently brushing, rinsing with warm salt water 2-3 times daily, and avoiding chewing on that side, while using a simple pain reliever. However, the most important step is to visit a dentist for examination, and if required, an X-ray to identify the exact cause. Treatment may involve cleaning the area, removing trapped food, treating decay, or managing the wisdom tooth if it is the source. Seek prompt care if pain worsens, swelling returns, or you develop a fever or difficulty opening your mouth.

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.

A toothache that has lasted for 3 days and is getting worse usually means there is an underlying dental problem, such as tooth decay, infection, or gum inflammation, that will not settle on its own. For immediate relief, you can take a simple pain reliever like paracetamol, avoid chewing on the affected side, and rinse your mouth gently with warm salt water to reduce irritation. However, these are only temporary measures; the most important step is to visit a dentist as soon as possible for proper examination and treatment, which may include cleaning, filling, root canal treatment, or extraction, depending on the cause. Do not delay care, especially if you develop swelling, fever, or severe pain, as this could indicate a spreading infection that needs prompt treatment.

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.
