Pain in Lower Left Abdominal and Left Testis along with its connecting Chord after getting ALL(leukemia) treatment!

I have had treatment for Acute Lymphocytic Leukemia that was diagnosed in June, 2008. Now I am on the maintainence therapy and I am in Remission by grace of God. I had started feeling abdominal discomfort in my left lower side almost 10 days ago. Initially it seemed like a muscle streching at that part of abdomen because it used to feel as if it is just in the muscles just underneath the skin when I pressed by left lower abdomen just on left on my bladder. It also felt to me in the same area, when I streched my left leg forward. In mean time i was also having semi formed increased frequency of stool.
But as the days passed, the pain in that lower left abdominal area has decreased a lot though i feel it yet a little, while i press it. But I still feel often need to pass stool (a feeling that you have when are having loose watery stools), though stools mostly come in normal or semi formed consistency.
I had reported about this problem to my clinic and the junior hematologist at duty there had ordered abdominal ultra sound along with testicular ulatrasound. The sonographer doctor performed ultrasound three days ago but didn't notice any abnormality in my testi or my abdomen or kidneys.
