Small red spots on the leg that do not fade when pressed
Small red spots on the legs that do not fade when pressed may be caused by conditions such as telangiectasia, allergic purpura, or pressure purpura, and timely medical treatment at a hospital is necessary. Specific causes are as follows:
1. Telangiectasia
Long-term exposure to ultraviolet radiation or cold and heat stimulation may lead to the appearance of small red spots on the skin. Under a doctor's guidance, topical medications such as tretinoin cream or salicylic acid ointment can be applied for treatment.
2. Allergic Purpura
This condition may result from infections, drug allergies, pollen allergies, and other factors. It involves an allergic inflammatory reaction affecting small blood vessels throughout the body, which may manifest as skin spots. Under medical supervision, medications such as levocetirizine hydrochloride tablets or diphenhydramine hydrochloride tablets can be used for treatment.
3. Pressure Purpura
This is usually caused by venous reflux obstruction leading to blood vessel rupture. Increased intravascular pressure is often due to severe coughing, which may result in bruises and petechiae of varying sizes on the skin. Under a doctor’s guidance, medications such as pediatric cough syrup or pediatric expectorant and antitussive granules may be used for treatment.
In addition to the above causes, such spots could also be due to leukemia, hemophilia, or cherry hemangiomas. It is advisable to wear loose, comfortable clothing and avoid prolonged friction.
