What are the symptoms of being stabbed by sea urchins?

Soon, edema erythema and occasional blisters appear around the wound. After about 1 to 2 weeks, the rash gradually subsides. This local skin symptom is immediate type allergy.

Granulomatous nodule is a kind of delayed reaction. Within one year after stabbing, round hard nodule with the size of 0.2-0.5cm appeared locally, single or multiple. The surface of the nodule is verrucous, hard, light red or cyan, later yellowish brown, surface keratosis, some nodule surface is crater shaped, generally no pain or mild tenderness, mostly in the hand. This kind of granulomatous nodule may be that the tip of the brittle and easily broken thorn remains in the skin after the sea urchin stabs the skin, and a foreign body granuloma is formed several months later.

Invasive plaque is a delayed reaction, which can occur simultaneously with granuloma or independently. Within a few months after the skin was stabbed, diffuse dark red infiltrating masses appeared in the local area, which mostly occurred in the fingers. Later, the fingers may have fusiform deformity, and have symptoms of localized bone destruction and synovitis of adjacent fingers, which limited the movement of the fingers. This kind of symptoms can not be cured for a long time, and a few can be naturally absorbed.
