Severe Edema after stapler circumcision.

I have undergone Stapler circumcision 7 days ago. During first two days (when there is dressing around) there is minimal pain and no swelling around penis area. After removal of dressing, when penis got shrinked, the next day there was swelling and band like structure formed above the plastic ring and there was too much burning sensation and pain. When I consulted urologist yesterday (on 6th day after surgery), he said there is infection around the area because of plastic ring and using 5ml syringe at 3 different places (drained out the liquid in yellow and red color) and removed plastic ring too. But, that band structure is still present and swelling of that band is somewhat reduced. Will it become normal and band will get disappeared or how long will it stay ? There is slight burning sensation around the area. Currently EroxCV625 is recommended by Urologist. Please suggest
