My face is changing. I have puffy cheeks, tired eyes with darkening under my eyes, and my midsection --- abdomen has spread like I am gaining weight, but I only eat one meal a day because I don't know why my face and midsection are gaining weight. I weigh 146 lbs. at this time. I was over 150 lbs. three weeks ago. I stay at 143 to 145 lbs. usually. I have constant pain on the left side of my abdomen. I get extreme, severe pain on my left side every 7-10 days, for about 30 minutes and then it goes away. I know there is something wrong with me.
