Hi after 40 days of my hydrocelectomy there is still swelling as double or triple than other testicle and pain in the firm part of that? What I do?

Here are some... Despite 40days after hydrocelectomy, the most reasonable medicine is still time and patience since the "final" surgical resolution may take 6-12 months to "complete" as long as being mentally and physically comfortable. If wishing to chat in person, go to Concierge at www.HealthTap.com/dr-Lin with keycode at RQPWJC. Best wish to health, happiness, and success...
More time. Give it about three months or so to resolve. If not better, see your surgeon for an exam. Hope this helps!
