Yes it does. No way around it. However, when doing shockwave treatment, while completely subjective, we are searching for pain that is 7 out of 10 on a pain scale, and thus could get very uncomfortable. Once we find locate a pain point, we keep it on that spot until the pain subsides down to about a 3 or 4 until we locate another spot. Some parts are more sensitive than others and can could peak higher than a 7 (but never to a 10).
Though it might sound intimidating, the entire treatment is done to patients tolerance and should immediately dial the intensity back if the patient says it is too much for them.
