Is this a suture abscess? Do the dissolvable sutures need to be removed? Why do I keep getting these wounds? (Photo)

I talked to my doctor on the phone today and she explained what she thought was going on. She didn't see me but She said my body is trying to push the sutures out and gave me instruction on how to care for the wound. But, I've been reading other comments about this and many doctors say that the suture needs to be removed in order to heal. My doctor didn't mention anything About removing it. Does it really look like a suture abscess? How can I prevent these wounds? Will it cause worse scarring?
