Question: My son is two years old and has a hard lump about the size of a quail egg near the base of his thigh on one side, embedded under the skin. It was discovered six months ago, and a doctor initially attributed it to “internal heat,” advising more water intake. However, after six months, the lump hasn’t gone away and has actually grown larger. Could this be serious? If we go to the hospital, which department should we visit?

Answer: If the lump is located in the front (groin area), it may be enlarged lymph nodes, suggesting possible athlete’s foot or tinea pedis in the lower limbs. If it’s in the back (below the buttocks), it could be a tendon sheath cyst. If there’s no pain, no treatment is necessary.
