i am a 20 year old female. since january i have made an effort to lose weight through diet but have now joined a gym. i have noticed that on my stomach and chest it feels like liquid filled with lots and lots of little lumps. they are not painful but i have never felt them before. i have also been drinking protin shake advised by my personal trainer to help me tone. are these lumps are a result of exercise or should i go see my docter.
