Piles, fissure. Will cure after surgery?

Iam 7 months pregnant now. Am suffering with piles and fissure since long time .last year the pain went high and consulted doctors ,they suggested medicine n cream . And said if it was cured by those medicines ,ok. Else I need to go for surgery. Parellely I've taken homeo medicine too which helpsme to reduce my pain alot . Now I dropped that medicine bcoz gynaecologist suggested me to stop that. Now since last ten days iam fealing pain again and as iam pregnant ,I can't go with surgery now May I prefer surgery post 3 months of delivery ,how can I get relief now ? Is fissure surgery  dangerous ? Will fissure n piles will cure after surgery? I know ,i have to take more veggies m fruits n high fibre diet and am taking those . But I think I need to go with surgery for sure after delivery.
