The stuff is REALLY cold!! It is a menthol based spray that immediately cools the affected area and you feel it working for up to 3 hours afterwards.
I used it on a back injury along with some Ibproufen and was pain free the next day. I find it really comes into its own after a long run and my shins feel a bit tender. One blast and it is like standing in an ice bucket.
Don't spray the stuff in a confined space though... The menthol, (like Vick's but 100 times stronger) with make your eyes pish themselves.
Now here is someone who knows what they are talking about telling you about the stuff....

Deep Freeze Cold Gel cools the skin bringing about rapid pain relief. Deep Freeze Cold Gel combines the proven principle of cold treatment with the benefit of gentle muscle massage. Available in 35g and 100g pack sizes.
When would I need a cold topical treatment?
For acute injuries such as sprains, strains, kicks and knocks - the type of injury you might get while playing a sport, or bending and lifting - which frequently result in swelling, inflammation and bruising, as well as pain. Cold treatment, applied immediately (or quickly) after injury is the preferred method to help numb pain, reduce swelling and inflammation and bring out bruising.
How do cold topical treatments work?
Cold topical preparations are a convenient alternative to the traditional ice pack. They numb pain and reduce inflammation. That is why physiotherapists recommend the RICE principle:
Rest (to aid recovery)
Ice (to reduce Swelling)
Compression (a close fitting bandage)
Elevation (raised support for injured limbs)
Which formulation should I use?
For an instant burst of cool relief to ease the pain of sudden injury, or for difficult-to-reach areas, use Deep Freeze spray. For longer-lasting relief, and when using the RICE principle (see above), Deep Freeze Cold Gel brings the benefits of a cooling action with soothing massage.
Why is Deep Freeze so effective?
Deep Freeze spray delivers instant, cooling pain relief. Deep Freeze Cold Gel is cold on application and in laboratory tests; its cooling effectiveness was compared to that of natural ice. Although the natural ice initially cooled the skin to a greater degree, the cooling effect of Deep Freeze Cold Gel was long lasting. The use of ice beyond 10 minutes can be unbearable on the skin for most consumers.
