For knee pain and stiffness from starting cricket, you can apply a topical diclofenac gel to the affected area 3 to 4 times daily. For oral relief, mild pain relievers like paracetamol or ibuprofen can help reduce discomfort; remember to take oral ibuprofen with food. Alongside medication, practice the RICE protocol: Rest the knee, apply Ice for 15 minutes, use a compression sleeve, and elevate your leg. Gentle stretching before playing is also highly beneficial. If the pain persists beyond two weeks or is accompanied by swelling or locking, please consult a doctor for a physical assessment. This is a very common response to starting a new sport.
