For menstrual cramps, over-the-counter NSAIDs (Non-Steroidal Anti-inflammatory Drugs) like Ibuprofen (200-400 mg) or Naproxen are highly effective because they target the prostaglandins that cause uterine contractions. Always take these with food to protect your stomach. Alternatively, Acetaminophen (Paracetamol) can help but may be less effective for cramps. Applying a heating pad to your lower abdomen and staying hydrated can also provide quick relief. If your pain is severe, worsening, or not relieved by these medications, please consult a doctor for a personalised evaluation.

For immediate relief from tooth pain, you can take paracetamol or paracetamol with an anti-inflammatory. Rinse your mouth with warm salt water and avoid very hot, cold, or sweet foods. This will give temporary relief only. A cavity needs dental treatment (filling or root canal). Hence, please see a dentist as soon as possible to fix the cause of the pain.

For widespread back and neck pain, over-the-counter options can provide effective relief. You may try acetaminophen to help reduce pain, or a nonsteroidal anti-inflammatory drug (NSAID) such as ibuprofen or naproxen to target both pain and inflammation, provided you have no underlying stomach or kidney issues. Applying a warm compress to relax the muscles or an ice pack to reduce inflammation can also help. Please follow the package instructions carefully. If your pain is severe, persists for more than a few days, or is accompanied by numbness, tingling, or weakness in your arms or legs, please consult a doctor for a personalized evaluation.

For temporary relief from severe tooth pain due to a cavity, you can take an over-the-counter pain reliever like Ibuprofen (400 mg) every 4 to 6 hours, as it helps reduce inflammation. Alternatively, Acetaminophen (500 mg) can be used. Always take these with food to avoid stomach upset. Do not place any pain relief tablets directly against your gums, as this can cause chemical burns. Please remember that medication only masks the pain temporarily; it does not cure the cavity. You must consult a dentist as soon as possible to treat the decay and prevent a deeper, more painful infection.

Your symptoms suggest a pinched nerve in your neck (cervical radiculopathy), likely aggravated by cracking your neck, which you should stop doing. For temporary relief of pain and inflammation, you can take over-the-counter NSAIDs like ibuprofen or naproxen, or acetaminophen. However, because you have numbness in your hand, a sign of nerve compression, medication alone isn't enough. You must consult a doctor for a proper physical exam. They may prescribe nerve-specific medications (like gabapentin) or recommend physical therapy. Avoid sudden neck movements and seek immediate medical care if the numbness worsens or weakness develops.

For throat pain while swallowing, start with symptomatic relief. You can take over-the-counter pain relievers like Paracetamol or Ibuprofen to ease the pain. Warm salt-water gargles, throat lozenges, and staying hydrated with warm fluids will also help soothe your throat. Please avoid taking antibiotics without a doctor's prescription, as most throat infections are viral and antibiotics will not cure them. If your symptoms are severe, accompanied by a high fever, difficulty breathing, or persist for more than 3 to 4 days, please consult a healthcare professional for a physical exam.
