Knee pain while going up and down stairs is commonly due to Patellofemoral pain syndrome or early wear of the joint. Rest the knee, avoid excessive stair use or squatting, apply warm compresses, and do gentle strengthening exercises for the thigh muscles. You can take simple pain relief like Paracetamol if needed. If the pain persists, worsens, or there is swelling or instability, consult an orthopedician for proper evaluation and physiotherapy guidance.

It is best to consult a doctor or physiotherapist who can assess your knee and recommend exercises to strengthen the surrounding muscles, which help support the joint and reduce pain. Rest your knee, avoid lifting heavy weights, and use ice packs or painkillers such as paracetamol or NSAIDs under medical supervision.

For severe period pain, over-the-counter NSAIDs (Non-Steroidal Anti-inflammatory Drugs) like Ibuprofen (400 mg) or Naproxen are the most effective options because they directly target and reduce the prostaglandins that cause uterine cramping. Take them with food as soon as your pain starts. Applying a heating pad to your lower abdomen and staying hydrated can also provide significant relief. If your pain is debilitating, does not improve with these medications, or is accompanied by unusually heavy bleeding, please consult a gynecologist. You may require prescription-strength medicine, hormonal treatments, or an evaluation to rule out underlying conditions like endometriosis.

For sudden, severe back pain, you can temporarily take over-the-counter NSAIDs like Ibuprofen (400 mg) or Naproxen to reduce pain and inflammation, or Acetaminophen (Paracetamol) if you cannot take NSAIDs. Apply a cold pack for 15-20 minutes to numb the area. Since the pain is severe and limits your mobility, please consult a doctor for a proper diagnosis before starting any stronger medication. Seek immediate emergency medical care if you experience 'red flag' symptoms such as numbness in your groin or legs, weakness, or loss of bowel or bladder control.

Severe one-sided pain behind the eye with a throbbing feeling that comes back after the painkillers wear off is most commonly due to conditions like cluster headache or migraine, though sinus infection or nerve-related pain can also cause similar symptoms. Because the pain is recurring and intense, simple medicines like ibuprofen or paracetamol may give only temporary relief and are usually not enough. For proper treatment, a doctor may prescribe specific medicines such as Sumatriptan for quick relief during attacks, and preventive medicines like Verapamil if the episodes are frequent. It is important to identify and avoid triggers like stress, lack of sleep, alcohol, or strong smells, and maintain a regular routine. You should consult a doctor, preferably a neurologist, for an accurate diagnosis, especially if the pain is severe, one-sided, associated with eye watering or nasal symptoms, or persists for weeks, as early and targeted treatment can significantly improve your condition.

Brufen 400 Tablet (Ibuprofen) is an anti-inflammatory medicine that can help reduce the swelling and pain in your finger. However, since your finger is still swollen and has started hurting after ten days, it is important to have it examined by a doctor. A physical examination and possibly an X-ray are needed to ensure there is no fracture or other complication that requires specific treatment.
