rectal pain after radiation for anal cancer included a fissure, which did not respond to creams until PA at Mayo Rochester gave a compounded cream Nifedepine 2% That is the worst pain i could imagine,
she also gave me vaginal suppositories that have a valium component for rectal pain ,,,,,,,,never heard of that, but it works to relax the rectal area
I also use silverdene cream compounded RX for rectal burning as well as Proctomed cream RX all perscribed by my radiation nurse at Mayo Rochester,, She also gave me
Xerofoam Petrolatum dressing by Curad .. overlays across rectal area I used those for weeks , soothing and can be ordered on Amazon or radiology nurse gave me some to get started
Opiods required laxatives and stool softeners to lessen friction on the fissure
Also w radiation I have learned tha the rectal canal can shrink just as the vagina does, ( scarring) so I had an in office rectal dilation by a GP locally in NC ,once I got the skin burns to subside with the Xerofoam , Silverdene cream compound and Aquafor .it Sitz baths at least 2 x a day when rectal pain is intense and before and after BMs
i have used Gabapentin and Lyrica too for nerve pain,,
Dr Sood one of the directors at Mayo Rochester Womens Health is assisting me with vaginal issues I do not have vaginitis , just scaring I really like and trust her . I have some neruopathy in feet and weakness in legs so going to PT and as always, Accupucture Best wishes on your arduous journey,, let us know how you are doing !
