Bengay ultra strength actually works well at relieving pain from muscle issues, arthritis and any other deep tissue pain you might be experiencing. It is very strong though so use sparingly. I have bad neck and back pain and like to massage in pain creams to help on my bad days. This product is warm, well hot really, after you start rubbing it in. The heat is what I feel helps the most at relieving my muscle aches, it sort of releases the tension in my muscles that causes my pain. If I use to much the heat is more of a burn and it does not feel good! It says on the box not to use with a heating pad and I can see why they put that warning on there. Adding heat to already existing heat will cause you to burn. It has a very strong smell and if you use it close to your eyes they start to water and sting a little. I have to use medical gloves when I apply this because I fear I won't be able to wash it all off and I will touch my eyes. Overall though it does what it claims.
