Earlier this week (maybe four days ago), a pain started to develop just below my ribs and in my gut region. It felt like that whole region had been twisted. I didn t do anything particularly taxing this week, just working at my office. When I look in the mirror and stretch my arms upwards, the bottoms of the left and right sides of my rib-cage seem to be out of line. There is a dull ache when I m sitting or walking, but it becomes more pronounced when I m lying in bed (for instance, last night it stopped me from getting to sleep). To give you some background, I have occasional back problems, calcium deficiency and I require testosterone suppliments. Any suggestions or advice you can give would be greatly appreciated. Thank you!
