Stomach issue

[OuchStomach]

I would love some help with this please.

I am a healthy 28 yr old male.  About a week ago I had a weird sensation on my left pelvis.  Not pain, just something that didnt feel right.  Since then I have been extremely gassy, get a bloated feeling often, gurggling in my stomach, and quick stabs of nerve like pain in my pelvis and man parts.

I have watched my stool and for one day it seemed flat.  It has been smaller than normal since, but not pencil thin like i hear described.  More like 4 pencils, but deff a reduction in size from normal.  Its the right color though and no blood.

Symptoms Brief:
Fullness feeling in stomach.
Gurgling from stomach.
Thinner stool.
Stinging pain in pelvis and reproductive organs.

I think I have gained about 5 pounds, but not changing diet, and no loss of appetite.

All this is one weeks time.  I read how cancer can make it flat and then thin, but it was flat for only one day, and since has been small.  I doubt cancer acts that fast.  I would assume cancer would act much more gradually.

I went to my doc today, and he said he could not find a hernia and took my blood and ****.  But thats going to be a week to get back, and this feeling is not going away.  I have had no change to my eating or lifestyle.

All I know is one day, I had that weird feeling in my pelvis while going to the bathroom, and since these symptoms are here.  Does anyone have any idea?

Sometimes the internet can scare the heck out of you!  At your age with no family history, I doubt it is cancer.  There are a lot of other things that could be going on, what is important is that you are being pro-active and not waiting on this!  Catching anything early, even cancer is a big positve step towards recovery.  I know it's scarey, but don't worry until you know if there is something to worry about.  My son had his colon removed at 12, and then about a year later started bleeding from his rectum, of course I panicked, thinking the worst.  It was just some inflammation, and he is a healthy 38 year old today.  So, I do know how scarey this can be, but I think you'll be fine (his problem was due to a hereditary disease).

Update:  Past two days Ive been more tired.  GF noticed it even.

Less paing in man parts now, less pain in stomach, but still feel full at all times of day.  Couldnt eat a whole sandwich either as I started to feel a little nautious.  To be honest, I think I am driving myself crazy with worry since everything on the internet says Colon Cancer.  I have an appointment tomorrow with a Gastro.

Current symptoms:
Full feeling/bloated.
Less energy than normal (even though I normally drink alchohol and get less sleep than I have this week)
Have gone to the bathroom, but never feel emptied.  
Now to get a lil grosser.  I strain to go to the bathroom and when I strain harder I can feel pressure on upper left pelvis.  When it comes out it is in small pieces (maybe 2-3 inches long) and very narrow (about the width of a dry erase marker.) Often it is flipped up at the end or curved.

I understand that with many colon related things bleeding is common, but it looks completely normal color wise.  There may have been 1 day over the weekend where it appeared dark, but that was only 1 day, and after Mexican. :)

My fears are still telling me colon cancer; I'm only 28 though with no family history.  I still can get stuff out, and it is thin and in small fragments, but no blood.

In the morning I can get out a few good pieces before I start having to strain and get the smaller stuff....which leads me to think/fear  there is a blockage about 12 inches up....so as I sleep its forming under a block fine, but once I clear that out, I am pushing whats behind the block through.

I guess tomorrow I'll talk to the expert....I just hope I feel better; and my symptoms, if worst case, do not seem as bad as other people who have had it.  I am not totally blocked, I'm not throwing up, and I don't see blood, and Im not pencil thin.

Of course, if I read right people with butt problems feel fatigue due to becoming anemic because of losing blood.  Since I see no blood, and its not black, I doubt I'm lossing blood, so fatigue may indeed just be worry/stress I've put on myself worrying what I have.

Anyways, maybe I just typed all this cause I am panicking myself to death after reading the internet.

May be of interest, in February I took 2 days off work because my stomach didnt feel well, and I felt constapated.  Could be a link? Not sure....just worry.

Any ideas out there, or similarities to anyone?
