My multiple experiences with abdominal surgery suggests:
One or two occasional 10 second shooting pains you described might just be normal healing.
For example, it might
be the beginning of a natural erection and the pain sensation similar to those pains experienced by patients that try some Bi-Mix injections or Muse suppositories?
However, if it is debilitating, unmanageable pain and occuring with increasing frequency (not just an occasional annnoying or unusual sensation),
- I'd make an appointment and discuss it with my physician.
I can't say I have ever had more than just an occasional passing sensation even similar to the one you described - something somewhat similar and fleeting while creating an erection with a pump and/or Seldenafil.
It doesn't sound like the suture or strained suture pain that is common in abdominal surgery.
While your idea that it is nerve regeneration could be accurate, the locus, increasing frequency, amplitude, and duration described suggests to me your pain should likely be evaluated by your physician.However
, if it is accompanied by a natural erection and the pain subsides, you are instead to be congratulated..... CCedar
