String like vein on penis. 3 months.

I was diagonised with bilateral grade ii varicocle with infertility (terato zoo spermia). Urologist suggested for micro varicocelectomy. Undergone micro varicocelectomy on left side. After 5 days of surgery i could feel a sharp vein (cord like) passing from incesion area to head of penis. During erection it is vey prominent. Also near head of penis when i lift skin, i could see bulged blood vessels with some clots.. During erection both cord like vein and bulged blood vessels are prominent.. i visited my surgeon to explain situation.. but that time my penis was small and doctor couldnt feel it.. he simply said thats normal and gave evion 400 mg tablets...also there is a decrease in the volume of semen coming out.. dont know whether the vien and blood velssels will burst during sex.. fully tensed.. doctor said me to take sperm check after 3 months.. i feel like i added new problems rather solving infertility.. pls help
