Regarding inflammation, it is difficult to say one thing that applies to everyone. It depends on how big the inflammation is, if it is acute or chronic, if it is red, throbbing and warm, you should avoid cupping at the area as it will only irritate even more. While in some cases it is good to cup to start the circulation, start gently (a few minutes) and see how the body reacts, so that it does not get irritated. Start by trying to cup around the area instead, which means that the effect of increasing circulation can also spread to the irritated area so that the flow increases even there without the need to cup directly. If you are unsure, check with the person who made the assessment of the inflammation.
