Seema to be fissure. Any surgery.

Yesterday, in the morning after defecation I found there was a lump which had swollen very much. I have heard of piles and Fissures earlier, so I tried to check if the lump had come out from inside the rectal cavity or not. I found the lump is a lump which has a single skin with the outer skin of my body that is has the same external skin as the exterior of the rectal cavity. So I guess it is outer skin swollen due to a crack. Also, I tried to gently push it inside to see if it goes back inside but no it just went till it joined the other contractive muscles of the rectal hole. Kindly help me with suggestions if I need to check anything else, kindly help me find a doctor on Practo, (female doctor more preffered for this case) if not any good proctologist is okay. I can visit and get a consultation. I stay near Whitefield area. Please guide. Little scared as I am unable to see and make sure of the actual problem. Want to be sure that it will heal without any surgery.
