Post Vasectomy problems

My husband had a vasectomy 3 weeks ago. He has been in pain every day since .
Firstly they went nearly black and swollen and then the stitches went a bit pus filled on one side and again his balls were huge and he was in mega pain . He was given iodine which was rubbish so i made him go back to a different dr the next day who was quite shocked and gave him fluxocillin(unsure spelling). A swab was also taken at this time.He still was in pain but his balls reduced size a bit.
The fluxocillin course ended and the infection came back. swab results didnt come back and no one bothered to chase them up despite me keep ringing(told they may take 3 weeks!). So balls got massive again and another lump has appeared at the bottom back of the ball sack . They have put him on Erythromycin which is giving him stomach pains and i havent seen much improvement (3rd week now) , balls still the size of a large jacket potato and quite red. What happens now? I am getting really worried now as i din not expect any of this.

6 days after having my vasectomy my stitches started to come out. The problem is the incision did not heal. I did not do any of the things the doctor told my not to do. Did not lift, run, etc.
I call my doctors office. I was told by the doctors office nurse this "happens sometimes". "Put a band aid and some neosporan on it and keep it clean". This did not make me feel any better. I have a 1/2 inch cut in my ball sack going east to west at the base of my penis and its wide open.
The next day I called the doctor again. This time the doctor talked to me. He said not to use neosporan because it was oil based ( bad advise from his nurse ) and just keep it clean. I was told some doctors don't even use stitches. The incision would close on it's own in a month. Today is 14 days from the procedure. I have a round donut looking wound. 3/8 in Diameter and 1/4 inch deep. Doesn't seem infected but it's always damp and oozy.
Knowing what I know now. I would not have let him make an east west cut. I think the weight of my balls kept the incision from healing.
