Severe joint pain in the hands for more than two months may be due to inflammation, arthritis, or joint strain. It is important to get it checked by a doctor, who may recommend blood tests or an examination to find the exact cause. In the meantime, rest the joints, use warm compresses, and avoid excessive strain on the hands.

Back pain after lifting a weight is often caused by muscle strain or ligament stress in the lower back. Since the pain is worse while walking and better when sitting, it may be due to a pulled muscle or minor back injury. Try to rest, avoid lifting heavy objects for a few days, and apply a warm compress to the painful area. If the pain continues for several days or becomes severe, it is best to consult a doctor for proper evaluation.

Pain and swelling after a fall can be due to a sprain, ligament injury, or sometimes a fracture. Since you feel pain when putting weight on your ankle, it is important to rest the foot, apply ice, keep the leg elevated, and avoid walking too much. If the swelling or pain is severe or you cannot bear weight, it is best to get an X-ray and consult a doctor to rule out a fracture.
