Sometimes it is necessary to experience what is described as “the good hurt” when really working on an area of the body that you have been experiencing pain or achiness in. This is that feeling you get when having the area deeply worked on is in fact uncomfortable, but it feels good to you to have it stimulated. Usually if you are experiencing pain somewhere, it does in fact hurt a little too really remove the tension and adhesions that are causing the pain. This is normal and everyone has a different idea of where this level is. However, not everyone wants to get this out of a massage.
You should NEVER “suffer” through something you consider painful or uncomfortable unless that is the kind of work you are looking for. If too much pressure is being used simply ask your therapist to “go a little easier there.” All in all your massage should be a pleasant, comfortable experience.
