Thanks for your query.Based on the facts that you have posted it appears that you have undergone surgery of implantation
of Inflatable Penile Prosthesis
as a prt of treatment for Peyronies disease.
From what you have described it appears that the prosthesis that has been put has been infected giving rise to these symptoms and developing secondary hydrocele
It is possible that concerned Urologist
might have given you antibiotics and anti inflammatory medication .However since your symptoms are worsening I would suggest you to consult the operating surgeon to explore the possibility of redoing the surgery and place the implant in a suitable place.or remove the implant and redo surgery to put it again at later date when the inflammation gets subsided.
In the mean while continue taking antibiotics and anti inflammatory drugs .
