I went to the Emergency Room the other night, after cutting open the tip of my finger with crazy-sharp knife. Needed 3 stitches, preceded my two shots of lidocaine to numb finger. Finger is on the mend, but why am I 5 lbs heavier? This happened two days ago. My pre-injury weight is 112lbs at 5'3". have been taking a few Tylenol a day, eating what I usually do, which is very balanced and in moderation. Help!
