4 to 6 weeks seems a bit long, when she regulates/(figure out whats going on with her) I will try feeding lite and do 1 xl every 2 1/2 to 3 weeks. Pretty sure there is no blockage, we gave her a gentle soak today to see if it helps a little. Her swelling is about a foot long and not hard or stiff in anyway, pretty much just feels like fat very swelled and soft.
