Ice and heat are often used in treating injuries.
1. Ice packs are best for icing larger areas of pain, swelling, or spasm (like a swollen knee, deep thigh bruise, muscle strain, shoulder tendonitis, or neck or back spasm).
2. Ice bath/ice whirlpool is used to reduce swelling in peripheral joints (such as with ankle sprain, wrist sprain, or severe shin splints).
3. Ice massage is used to reduce superficial, well-localized inflammation (for example, tendonitis of the hand, wrist, or elbow; heel or elbow bursitis; ganglion cyst; apophysitis; or irritation of a growth plate).
