I noticed during the summer, while I was in this program that gave us unhealthy meals for five weeks (I had to be in this to get into a college), that when I had my backpack on a little air bubble or pocket was built up in my vein. I did not want to press on this bubble at all because I was afraid. This never happened before and would like to know if it was from eating unhealthy, salty foods?, for five weeks. After this program, it had decreased, but I can still feel a tingly sensation in my left arm.
