new mom: help with pumping

Hi there! 
So I've been pumping after every feeding trying to increase my supply (per my lactation consultant) I'm also taking fenugreek and blessed thistle, as well as eating lactation cookies. My right side has shown some improvement but my left side refuses to produce any more. 
I was wondering if anyone else has experienced this and what you have done?
My left nipple swells in the Falange and the consultant said I just needed a bigger Falange and it would help with production as well. Yes here I am with the xl size from Medela and it's still swelling up during pumping sessions. 
Please help! My little guy is two months today and eating 4 ounces at bottle feedings. My right side produces 2-3 ounces during an exclusive pumping session, but I'm lucky if I get one ounce out of my right side.
Any advice would be great
Thank you!
