I'm 16, 5'5, about 155 lbs, and female. I have been getting random stomach aches and occasional heartburn for about 3 years. I assumed that it was because of my tendency to over eat and that fact that I was rarely exercising, because I was depressed. But now, I am exercising everyday, but I am still getting random stomach aches even though they do seem less frequent and I am rarely getting heartburn. I also have two other problems that concern me. It may not mean anything, but my hands, feet, and legs fall asleep very easily. Sometimes they just fall asleep randomly. This hasn't exactly been going on for a period of time, but it seems to get steadily worse with time. The final thing that I am concerned about is many random bruises have been appearing on my legs for about the same length of time as I have been getting the stomach aches. I always notice them after I wake up or while I'm in the shower. I used to believe that they were because I am clumsy and I tend to run into things a lot, but now they are turning up in places like the back of my thigh where I know I didn't bump into anything.
