The Paingone FREEZE Cooling gel is the next exciting product in the paingone range. It is a topical cooling gel that can be effective for: Arthritis Bad Back Sciatica Stiff Knee and joints Stiff muscles Aching muscles Sore shoulder Sports injuries How It Works The Paingone FREEZE Cooling gel works via a ‘counter irritant’ mechanism. Where the menthol in Paingone FREEZE Cooling gel creates a sensation that overrides pain signals to the brain. This process is known as ‘ Gate Control Theory’, where nerve impulses from one stimulus – the cooling menthol, block the nerves containing pain signals to the brain. Recent research also suggests that menthol may stimulate cold receptors in the skin that may help regulate pain as well. Paingone FREEZE Cooling Gel can be used in combination with Paingone to effectively target pain. Apply the gel after using paingone up to a maximum of 4 times per day.
