Pumping is pissing me off

Not only is it driving me nuts too sick forever and pump but the flange keeps leaking and losing precious milk down my stomach. I feel like my hands are cramping and I'm getting cramps in my elbow from holding the flange to my boo forever. The lactation Consultants I've talked to you said the plans I'm using is the correct size I'm using the smaller Medela one. One of the lactation consultant said to take an old sports bra cut slits into it and make that a holder for the flanges butt that drives me crazy too. Any other suggestions from anyone?
