My son has cysts filled with fluid on his spleen> He had to have them drained again yesterday which he says is very painful. The whole spllen problem is due to trauma to the spleen while taking his black belt test. He is in the marines. My question is what causes these cysts to fill back up?
Hello! Thank you for the query. It is unknown why such cysts appear. Trauma can be the reason of it. However, if it is large enough, and recurs after a Chat Doctor.
