For arm pain lasting two months, you can use over-the-counter pain relievers like ibuprofen or acetaminophen to temporarily ease the discomfort. Applying ice packs for 15 minutes a few times a day and resting the arm can also help. However, since the pain has persisted for several weeks, it is important to consult a doctor. They can perform a physical exam to find the exact cause, such as a muscle strain or tendonitis, and recommend a targeted recovery plan. Avoid heavy lifting or repetitive movements that worsen the pain in the meantime.

For temporary relief, you can take over-the-counter Acetaminophen (Paracetamol) 500mg to 1000mg every 4 to 6 hours (maximum 4000mg/day) or Ibuprofen 400mg with food. However, the combination of a high fever, severe headache, and back pain can be a sign of a serious underlying condition, such as meningitis, influenza, or a kidney infection. Because of this, you should not rely solely on self-medication. Please consult a doctor immediately for a proper diagnosis, especially if you experience neck stiffness, sensitivity to light, confusion, or nausea.

Waking up with a stiff neck is very common and usually resolves quickly. For relief, over-the-counter pain relievers like ibuprofen or naproxen can help reduce inflammation, while acetaminophen is effective for managing pain. Most strong muscle relaxants require a prescription, though some regions offer methocarbamol over-the-counter; you can consult a pharmacist about this option. Additionally, applying a warm compress for 15 minutes and performing gentle stretches can greatly ease the tension. If your symptoms persist for more than a few days, or if you develop numbness, tingling, or weakness in your arms, please consult a doctor. Otherwise, this should improve soon with basic self-care.

For immediate relief from severe gum pain, you can take over-the-counter pain relievers. Ibuprofen is highly effective because it reduces both pain and inflammation. Alternatively, acetaminophen can help manage the pain. Please follow the package instructions for correct dosages. Rinsing your mouth gently with warm salt water and applying a cold compress to your cheek can also provide temporary comfort. Since the pain is severe enough to keep you awake, it likely indicates an underlying issue, such as a localized infection, which requires professional treatment. Please schedule an appointment with a dentist as soon as possible for a proper diagnosis and long-term relief.
