For the past 4-5 months I get a strange sensation on my lower right side of my abdomen. It looks likes it is in the area of my appendix. It has happened maybe a dozen times in this time period. When it happens, it feels as if something is pulling, there is a dull aching pressure, honestly it kind of feels like something is going to burst. It doesn t last more than a minute if I hold very still and breathe slowly. It is very uncomfortable and alarming.
