Why does the body feel extremely itchy after gua sha?

Generally, experiencing significant itching after gua sha (scraping therapy) may be related to normal physiological responses, improper technique, dampness elimination, skin damage, or allergic reactions. Patients are advised to follow medical guidance for appropriate treatment. Specific analyses are as follows:

1. Normal Phenomenon

Itching after gua sha is considered a normal response. If the treated area feels itchy, painful, emits cold or heat sensations, or develops rashes on the skin surface, these are typically temporary reactions. It is recommended to avoid raw, cold, and greasy foods. After gua sha, drink a cup of warm water or light salt water. Additionally, refrain from bathing within thirty minutes post-treatment.

2. Improper Technique

Itching may occur due to improper gua sha techniques that damage the skin. In more severe cases, pain may also develop. It is advisable to seek medical treatment at a hospital if symptoms worsen.

3. Dampness Elimination

After gua sha, pores open up, allowing internal dampness to exit through the skin, which may cause temporary itching. It is important to keep the body warm after treatment to prevent invasion of cold pathogens.

4. Skin Damage

If excessive pressure is applied during gua sha, minor skin injuries may occur. During the healing process, mild localized itching may appear. This is a normal physiological part of skin recovery and usually does not require special treatment. To prevent infection, apply an appropriate amount of iodine tincture locally for disinfection.

5. Allergic Reaction

Gua sha oil is typically applied to the skin before using a scraping tool. Itching after gua sha may result from an allergy to the gua sha oil or the scraping tool itself. Patients may take antihistamine medications such as loratadine tablets or cetirizine hydrochloride capsules under medical supervision. Additionally, topical anti-itch lotions or washes can be applied to affected areas.

Besides the above, itching could also stem from inflammatory reactions. If noticeable discomfort occurs, prompt medical consultation is recommended to avoid delaying diagnosis and treatment.
