Anyone experiencing burning, stabbing, pins and needles?

I had my bilateral inguinal hernias treated on the 3rd June via the TEP procedure.

The only pain I am experiencing is an achey pain on both sides just in from the pelvic bone when moving or turning and a slightly more profound "sharper" ache when laughing, coughing, sneezing. This, I assume, is where the mesh was stapled.

My testes are aching aswell, but that's due to the extra blood/fluid in there.

I currently feel no numbness, no pinched nerves, no stabbing/burning/pinching pain. The incisions have never hurt, at all. They were glued back up again (no stitches).

I was on morphine and codeine (df118) post-op, Co-dydramol and diclofenac in recovery and am on diclofenac and paracetamol at home.

Am in the UK and had a brilliant surgeon.

The problem(s) that I am having is redness of my scrotum and penis. Although there is no associated pain they do itch. I thought that I may have been suffering from some kind of microbe invasion and have applied antibiotics to the area. My next thought was that an anti-inflammatory might help. I understand that the scrotum might have experienced some swelling/inflammation, but I didn't expect it to carry over to the penis. I also notice that the incision sites (of a bilateral hernia repair) are pink. What do you suggest I do?
