Kinesio, or Kinesiology, tape is a stretchy type sports tape that is excellent for supporting an injured area and relieving pain.
I use this tape all the time in my clinics and find it excellent for quickly offloading and supporting an injured area and providing fast pain relief. It is also used by some of my ultra runner clients for protection against blisters so worth a try!
I suggest that you seek advice before putting this on yourself to ensure safety and that you get the best use out of it.
Allergy risk is low but if you get any symptoms such as itching and burning with a rash under and around the taped area you should immediately remove the tape, wash the glue off the skin with warm soapy water and seek medical advice.
Applying this tape can affect and alter mechanical loading which may lead to painful symptoms. You should not use it if you are unsure of how to correctly apply it.
