I was in exactly the same boat as you reading exactly the same thing as you about performing 'surgery' on the shrimp!! Luckily I can to my senses and waited it out, the shrimp is perfectly fine and healthy, you would be surprised how many shrimp in your LFS have these lumps on their sides.
My advice would be to let it be and just monitor it on each moult!
