Leg and arm pains/cramps after excersise

[dreamsize8 0]

Alot of times after I excersise I get really bad leg cramps, pains in arms ect. that last for days before I can excersise again. Even as of late I wake up in the middle of the night with leg cramps. Had problem with one arm with wrist hurting that it wasnt able to move certain ways..and that comes and goes. My mother said I might need more potessium in my diet. Just wondering if anyone had experienced this after being banded. I often wonder if standing 8 hours at work 5 to 6 days a week is finally effecting me. Every job I ever had is standing/walking. I just want to get to excersie and get to my goal of 190 by sept 1st.
