I cannot recommend any specific tablet that is completely free of side effects, as all effective medications for joint pain may carry potential risks. Paracetamol is generally considered safe for most people when taken at the recommended dose and as directed. It is best to consult your doctor to determine the cause of your pain and choose a safe and appropriate treatment.

Your symptoms, particularly numbness and itching in the thigh along with knee pain, may indicate a compressed or irritated nerve. Common causes include arthritis, muscle strain, a slipped disc, sciatica, or meralgia paraesthetica (a condition affecting the nerve that supplies sensation to the outer thigh). You should consult your doctor for a proper examination and appropriate treatment.
