having been referred by my GP, I was examined (anoscopy? - large 6-inch long clear tube with camera inside) by an experienced anorectal surgeon this morning.
She said that any fissures have healed - and where not chronic enough to produce scar tissue. She also ruled out any LIS because there's no fissure to relieve pressure on.
She suggests that any pain (I still feel a level of pain equivalent to a stone in the shoe when walking every day) is due to 'residual tenderness of tissue post healing'
Advised me to cease all Rectogesic/Diltiazem - the side-effects outweight the benefits (not disappointed to hear this) - but to avoid constipation.
Anyone had similar? I have no reason to doubt her view as she was very thorough and professional. Just surprised as the pain is persistent, if not agonising.
