first constipation, now this

[PixelatedMe]

about a month ago, i started to feel my right testicle throb a little... not that that is connected, but i thought it may be... then a few weeks ago i noticed a cramp in my pelvic area.. it moved around but was mainly in the same place..  It seemed to be that i was just constipated.  though at 22, and this being my first time being constipated, i started to worry a little.  i got super stressed about it and the fact that i dont have insurance to get it checked out.  so a week goes by and the constipation is still present.  I pass stool once every 2-3 days, but when i do, it's really small amounts ( like a nugget the size of 1-2 grapes )  
it also seemed that i had gotten a urinary tract infection..

today, i feel REALLY full.. like my intestines are backup up all the way to my stomach.  if i poke at my stomach it aches.  also my tonsils seems to be swelled up bigger than normal (ive had huge tonsils for most of my life)  and it feels like theres something in my throat...

i realize that all these things seem kind of unrelated, but i'm just worried that they all are part of something going on with my body...

could this all just be stress?  what's wrong with me?
