pain from working and lots of it

I work in a bakery and standing up all day is killing me by night. Ive lost about 45lbs and you would think that the pain would start to ease up, but I hurt just as much now then I did before the surgery. I feel like I am losing all my weight mainly from the back side and I already had a problem with most of my weight being in stomach area just hanging. I can feel my stomach pulling on my lower back, hips and my feet on top and around ankles. I have started wearing a brace on my right ankle because it stays swollen and once I stop especially at night, hard to get moving again. I am going to go to the doctor sometime this week to see what he says, and if nothing else, at least thats a start to documation for my insurance for plastic surgery. I didn't want to have ps, but if I am hurting this much already, then how will I feel a yr. from now. I work out at Golds all the time and they were saying to try the muscle sculpting classes and that with this class, I would actually lose and tone more then doing weight machines. I ride 6 miles on bike and get in at least 30 min. on treadmill. With me having medicaid, which I should have another ins. from work soon, I hate to try to get something else approved. Probably a bunch of skinny individuals running that show!!! Well thinks for listening to my complaints. Nighty Night!!
