The way you are describing the situation, it really does not seem like a hydrocele
to me. Hydrocele presents as a uniform enlargement and not as multiple discrete lumps. As to what the possible diagnosis is, it is very difficult to say without a clinical examination. If the lumps are arising from skin they could be multiple sebaceous cysts. In any case an ultrasound
examination should clear up the mystery of what exactly is going on.
Thanks and get well soon.
