Hi!
I am sorry to hear about your medical problems. No, iloinguinal nerve is not cut during an orchiectomy. It can get injured during the operation.
The pain you are suffering could be due to Pudendal nerve entrapment (PNE). Treatment includes physical therapy, medications, steroid injections into the Aclock canal, pulsed radiofrequency, and decompression surgery. Use of ergonomic devices for sitting that remove the pressure off the nerve can be used.
Please consult your doctor regarding this. Take care!
