I feel you. I'm thinking needle is better now at this time too. Surgery is just . . . so . . . serious. Invasive and then there is recovery and all of that. I'd go or the easier and less invasive approach. It may come back and you may need surgery down the road but you can plan it when it is a good time OR be lucky to be one of the percentage of people that it doesn't reappear. So, I'm with you going with the needle aspiration.
When are you going to schedule it?
Did the needle aspiration work or has the Hydrocele returned? Why was the size of your Hydrocele and did the aspiration hurt?
