C. STRAINS (Home Treatment) Apply Arnica oil to reduce swelling. Do not apply heat during the first two days as this will only increase swelling. Thereafter, ibuprofen (or other non-steroidal anti-inflammatories) or aspirin is a good choice. Do not give aspirin to a child younger than 16 years. Remove rings immediately if the injury is to the hand or fingers. Use paracetamol for the first day of the injury, to reduce pain without increasing bleeding. After 48 hours, start moving the limb gently, but only enough not to cause pain. Gradually increase the range of movement - let pain be your guide. Apply the R.I.C.E. method.​
