Recovery Time
2-3 Weeks
Self Treatable
There is a wide variety of symptoms for this medical condition.
  1. Rest – stop the exercise or activities that caused the injury until you feel better
  2. Ice – put an ice pack (you could use a bag of frozen peas wrapped in a tea towel) on the injury for up to 20 minutes every 2 to 3 hours
  3. Compress – wrap a bandage around the injury to support it
  4. Elevate – if possible, keep the injured area raised on a pillow when sitting or lying down

To help prevent swelling during the first 2 to 3 days, try to avoid:

  • heat, such as hot baths and heat packs
  • alcohol
  • massages

When you can move the injured area without pain stopping you, try to keep moving it so the tendon doesn’t become stiff.
