Hi well come to HCM.
Question of main vein cutting does not arise at all if it happens there can be lot
of bleeding. So remove idea of cutting main vein. Yes there can be minor injury
there are bruses ie purple colour skin and some swelling.Take some antiinflammatory
drugs like ibuprofern or nimesulide
for two to three days you should be alright. If
not show it to your Doctor. On diverting mind every one looses erection, that is
normal need not worry about it, thanks
