dear dr's & friends

i had an lgx penile imp 2 weeks ago. everything ok .healing ok.still sore .very normal.while healing i found a tiny knot in the bottom of my left side of my penis only .seems like attachement of the rear tip extender or something.i asked my surgeon about it fearing a perforation after a while of using later to come.he replied that this is normal.like a hose when you bend it you get knots on the sides.but my other side is smooth.  or? might the surgeon install a longer rte? can someone give an answer please if they had or have  the same situation. thank you very much to all.ps surgeon said it won't be any perforation or problem
