If there is only minor swelling for a short period of time after the tattoo, this is usually normal. If the tattoo is accompanied by other discomfort, it is usually not normal. Tattooing involves the use of an inked needle to penetrate the deeper layers of the skin at high speed and frequency to create the desired design or wording. This can cause some irritation to the skin and the surrounding tissues under the skin. If there is only minor swelling, peeling, itching, etc., and normal crusting and scabbing for 3 to 5 days after the tattoo, it is usually normal. If there is still redness, swelling, itching and even ulceration for a long time after the tattoo, and the scab does not come off for a long time, it may be caused by the wound infection due to bathing, swimming and other reasons after the tattoo. If there is any discomfort after the tattoo, it is recommended to go to the hospital in time and follow the doctor’s instructions for treatment.
