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 of leg pain and numbness following a lower back injury suggest nerve compression, such as sciatica or a herniated disc. For temporary pain and inflammation relief, over-the-counter NSAIDs like ibuprofen can help. However, because you are experiencing numbness, which is a neurological symptom, you should not self-medicate. It is crucial to see a doctor for a proper physical evaluation and potentially an MRI. They can prescribe targeted nerve pain medications (like gabapentin) or physical therapy. Seek immediate emergency care if you develop progressive leg weakness or loss of bowel/bladder control.

For chronic back pain lasting two years, it is best to consult a doctor to identify the root cause. For temporary relief, you can use over-the-counter pain relievers like acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen, provided you have no contraindications. Applying topical pain-relief gels containing diclofenac can also provide targeted relief with fewer side effects. Because your pain is long-standing, medication is best paired with physical therapy and gentle exercises to strengthen your back. Please speak with a healthcare professional to create a safe, personalized treatment plan.

To temporarily relieve your pain and reduce swelling, you can take an over-the-counter non-steroidal anti-inflammatory drug (NSAID) like ibuprofen. If you cannot take NSAIDs, paracetamol (acetaminophen) can help ease the pain, though it will not reduce swelling. Applying a cold compress to the outside of your cheek for 15 minutes at a time can also provide relief. Please keep in mind that a loose molar accompanied by swelling often indicates a localized dental infection. While these medications will help manage your symptoms, it is very important to see a dentist promptly to treat the underlying cause safely and effectively.

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.
