I've been experiencing intermittent pain, soreness and tenderness in my right lower abdomen over the past few months. I was told that I might have gallstones but have been unable to get an appointment to have a scan done to confirm. Recently the pain has become worse, I can no longer lay on my right side or sit in certain positions without discomfort. I have the occasional night sweat and always have a dull ache and feeling of tenderness on my right side during the day.
