I am 62, male, 140 pounds. For the past 2 months I have been experiencing some prickly burning sensations along my lower left side and across my lower stomach area. This started in March with a sensation along my lower left side that appeared to also include some swelling along my lower left side - which swelling continues - though in the mornings it appears less to some extent. The sensations appear to be just beneath the skin - and at times have more discomforting that at other times - just short of being a low pain-cramp feeling. The burning prickly sensations seem to make the surface area to my lower stomach feel sensitive to touch at times. At times I seem also to experience pin pinching sensations along the surface areas of my skin elsewhere. I seem to have lost approximately 10 pounds of body weight in the past 2-3 months also. I first became aware of this as people continued to comment to me that I appear to be losing weight. I ve been speculating as to whether I might have some type of parasite, etc., that might be causing this. I ve been told it is not ulcers. Of course, I am clearly not knowledgeable at all in any of these areas.
