Fissure with Skin tag in Anal

My wife age is 36, she gave birth to my younger daughter in 2006, from then she got this fissure problem and skin tags formed in anal area, it's been 10years till now, we came to US, New Jersey in 2015, when we are in INDIA, she faced pain in anal during stool and blood in stool also, but that is not very often, I can say for every 4months or 5months in an average, when we came to US, the problem became more and since September 2016. the constipation problem and skin tags were not allowing to pass stool and pain in anal became more, we met gastro doctor, she recommended us to go for minor surgery, when I googled about her problem, surgery will relief for certain extent only, so I started moving to homeo, One of my senior in work is very good in guiding homeopathic medicines, and he is in practise since 20years, he suggested to take Nit Acid 200c, Nux Vomica 30 and sepia 30, along with that more fiber food, more water and sitz bath also. Before starting medicines, we started using tips like taking more fiber and drinking more water and once we got medicines from INDIA, we started using Nux only.. At this moment, she is out of constipation, hard stools, and blood in stool, but the pain in anal continuing and skin tags are still troubling to pass stool, can someone guide us to get rid of this fissure, pain and skin tags please... FYI.. at this moment only Nux 30 she is taking 5 round pills each time for 3times daily.
