Even if there is no bone injury, your symptoms may be due to soft tissue injury or nerve irritation from the fall. Tingling in the hand often suggests nerve involvement around the shoulder or neck area. Since the symptoms are continuing for a month, it is important to consult a doctor again for further evaluation to find the exact cause and prevent long-term problems.

It is important to have this evaluated by a healthcare professional, preferably your orthopedic surgeon, as soon as possible. While a late-onset infection six years after surgery is rare, it requires a proper physical exam and potentially imaging to identify the cause. Please avoid taking any leftover antibiotics, as this can complicate an accurate diagnosis. For temporary relief from pain and swelling, you can rest, elevate your leg, and use over-the-counter pain relievers like ibuprofen or acetaminophen if safe for you. A doctor will determine if prescription antibiotics or other treatments are necessary. Please schedule an evaluation promptly to get this safely resolved.

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.

For temporary relief from back tooth pain, you can take over-the-counter pain relievers. Ibuprofen (400 mg every 4 to 6 hours with food) is highly effective because it reduces inflammation. Alternatively, Acetaminophen (500 mg every 4 to 6 hours) can help manage the pain. Rinsing your mouth with warm salt water can also soothe the area. Avoid placing aspirin directly on your gums. Please remember that these medications only temporarily mask the symptoms. Back tooth pain is often caused by cavities, wisdom teeth issues, or infections, so it is crucial to see a dentist promptly for a proper diagnosis and treatment.

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.

For jaw swelling during a root canal, an over-the-counter anti-inflammatory medication like Ibuprofen (400 mg every 4 to 6 hours, provided you have no contraindications like stomach ulcers or asthma) is most effective. Applying a cold compress to the outside of your jaw for 15 minutes at a time will also help reduce inflammation. Please avoid self-medicating with antibiotics. Since swelling can indicate an active infection, it is crucial to contact your dentist immediately. They will determine if you need prescription-strength medications, antibiotics, or an urgent follow-up appointment.
