I have developed a pain in my left lower abdomen. It is most painful when I first get out of bed and generally goes away during the day. The pain radiates from  approximately 6 inches to the left and 2 inches down from my navel. close to my hip joint. This morning it was more severe than usual. I have been experiencing this pain for about 6 months shortly after purchasing a new mattress.  I am a 67 year old male in generally good health. I am also a Type 2 diabetic.
Hello, Thanks for posting on Chat Doctor, From your description, it seems to me you are suffering from abdominal muscle strain. Normally, when using a poorly designed mattress, it usually affects the back muscles and spines, but can also affect the abdomen. However, it will be best to get a doctor examine you in case you are having another internal problem such as a urinary tract affection, allopathic diseases, prostate disorder etc. Hope this helps
