This will vary but many patients experience immediate relief of their symptoms and an increase in range of motion. Soreness can also be a common response from the needling but does not occur with all people. Some individuals may experience an immediate achiness or a delayed soreness the next day. The soreness, if present, will usually last 1-2 days, use of heat and light massage and movement will be beneficial. Mild bruising may occur at the needling sites and is more prevalent in certain parts of the body. Larger bruising may also occur, but is rare.
Application of ice on the bruise will help with the soreness and the skin discoloration will last several days but is not harmful. It is uncommon but possible that the treatment may temporarily increase your symptoms. This is not unusual but if this continues past the 1-2 day window, inform your PT to allow adjustment of your program to enhance your comfort the next time. This does not mean that needling will not be beneficial to your condition.
This will depend on the category you fit in, which is determined by the state of the injury and your overall health. Remember we are attempting to cause mechanical and biochemical changes without any pharmacological means. Therefore, we are looking for a cumulative response to break the pain cycle. Your PT will be able to give you more insight after your evaluation.
