"i have psoriatic arthritis with lots of foot pain. i wanted an alternative to the drugs and anti-inflammatories normally prescribed and my doctor suggested this. after reading reviews i expected this to take away the pain immediately. it didn&#039;t, but knowing that everyone is different i kept trying and i&#039;m glad i did. now on day three my foot pain is much better, allowing me to walk. i have had no skin reaction. the smell of the ammonia carrier can be a bit overwhelming but it dissipates quickly."
