Hi, first off I would like to give a little back info, about 3 years ago I used to weigh 375 LBS, and my height is 6 2. Since then, I ve lost over 100 LBS and I m now weighing in at 260 LBS, with a goal weight of 200 LBS. Anyway, my question is related to this because I ve recently noticed an increased awareness of my organs, and I feel my ribs a lot more than Before. I assume this is because I have much less fat on my body, so this doesn t alarm me. However, for the past 2 months or so, I ve felt a little presence right under the left side of my ribcage, near my liver. I don t feel it all the time, only a few times a day, but sometimes it is accompanied by a slight sharp pain. The pain isn t bad, but I do feel it. What could this be? Another piece of information too: I compete in the sport of boxing, so I sometimes take shots to the body, so that could explain it. I am in very good shape, and I workout 9-11 times a week. Any insight would be greatly appreciated.
