Rectal Warts

I have aprox 4 internal warts that Itch like crazy I take a daily anti histimine for this, I previously have tried to treat them with Apple Cider Vinegar but this burnt and caused Fissures that took ages to heal.They warts just changed shpe from this treatment. I have also used an over the internet purchased electronic divice that sends an electrical signal to the wart applied by a copper wand, this did have some effect previously but does not seem to have any benifit really anymore. In regards to previous homeopathic treatments I have used Thuja 100c Globules 2nd daily for about three weeks and Sabina 100c on the alternitive days. eventually after stopping treatment with homeopathy the itching became controlled with a day strengh anti-histimine and not needed everyday ,this lasted about 4-5 months. but they are now back with a vengance. I now have 30c Nitric acid Globules that I have been taking for the last 3 days thre times a day, a little less itching I guess but they are still very much there and they still do itch. can someone help if this is the right treatment??,is it ok to add thuja to Nitric acid if so how much and how often??
