If bumps appear on the back after tui na, they are usually caused by a lack of qi flow or a heavy tui na technique that blocks the qi flow. Tui Na is usually unblocked, for example, the bumps can be dissolved or softened after tui na, and should not produce bumps. For example, some patients with subcutaneous stagnation may belong to a special constitution when they are pushed, and the qi can’t be dispersed for a while after the pushing, resulting in bumps, but this situation can be dispersed slowly in 2-3 days. If the patient has a special body type, i.e. bumps when pushed, then the patient may belong to a hypersensitive body type and it is recommended not to do massage. Many patients have subcutaneous lipomas, small subcutaneous nodules, small tumors, which belong to a special body type, many belong to the genetic nature. However, it is also appropriate to use the method of gua sha, the method of pulling cans, the method of unblocking the qi, some apply a certain method, which varies from person to person.
