Gave birth last June. 4th week after while passing stool, felt a tear and sharp pain comes after. When I feel around that area, realised there was a bulge near perineal and there is a skintag dangling

Till now, whenever I went toilet for big business, it gives me the sharp pain and it can last 3 hours or more. I have not went for my 6th week post checkup, as I am quite scared for the doctor to check that area. As for the skintag, i wanted to remove but scared of the pain as well as I can remember how they removed it for my first pregnancy. Is there any way for the skin tag to dropped and is there any cream to subside the bulge/swollen area?
