I too have had that permanent cut sensation. It has turned into a dull sensation post-LIS, but it is still there.
Fiss and others are right, by this point you should drop the proctofoam (I'm assuming that is what you were prescribed. I was prescribed some once by an idiot doctor, who later let the area abscess). Your drs should be prescribing one of three ointments, nitroglycerine, nifedipine, or diltiazem.
Even though your spasms aren't painful like charlie-horse-type spasms, they are what is making you constantly feel the cut because they are putting constant pressure on the cut. The spasms are also reducing blood flow to the area and thus reducing healing.
