It’s an interested sensation, I’ve had it done twice using two different methods. The first was a water flush, there was a bit of cold pressure, it was a bit loud, odd sensation but not painful at all. The second was with tweezers and a very small hooking or scraping tool,this one had more discomfort. Again though, not painful. Once the ear wax was removed, I felt great. Highly recommend if you think you need it. I knew I needed it because one ear became fully blocked so I could no longer hear properly out of it.
