Not sure if this is the right place for this

So I have been feeling bloated and like I can't pass gas without straining very hard since November 2013. I have a gurgling feeling on left side under ribs by the traverse colon. (not sure on spelling). I went to the doctor 12/9/2013 and he sent me for a CT scan said he didn't see anything unusual just a bit of poo by rectum and gave me a script for senna. Went home took it had watery stools and I had to strain quite a bit to get that out. 12/31/2013 still didn't feel right so I thought why don't i take magnesium citrate. Again nothing but watery stool. I thought perfect time to try Phillips colon health to get bowels right. For next 2 days i felt nausea and extremely full and having trouble passing gas so I stopped taking it. I went to the doc and he did a rectal exam and feels that maybe I have an impaction not by rectum but up higher. 1/3/14 he said to go home and do an enema then take senna before bed and to take linzess in the morning for 2 days. Then senna and linzess for a week. He assured me I would have a solid BM. I have had nothing but watery stools my stomach is a little hard after I eat. Is this normal? He said not to panic if the enema doesn't work? I haven't been eating much because I feel that nasty gurgling when I do. Could that be why my stools are watery? Is this the beginning of my IBS? Should I ask to be referred to a GI?
