Works well on sciatica and back pain. But a few downsides that I don't like:
1. It takes about 5 minutes to dry after applying (making it difficult to reapply during the middle of the work day).
2. It has a SUPER strong menthol smell that doesn't fade after it finally absorbs into the skin (can be smelled by others two rooms away).
3. It has a burning sensation in addition to the cooling sensation and actually sometimes leaves my skin red where it was applied to (like neck and upper shoulders, but not lower back and hamstrings), limiting where I could apply it. But I do have sensitive skin, so it may just be me.
I tried both the Cooling Roll-on and the Topical Relief Cream - while both work well, I much prefer the Topical Relief Cream and reordered that after finishing my first bottle.
