Hi I'm 16 years old and I've been experiencing weird pains in my pelvis bone which has radiated to the bone at the top of my left thigh and occasionally down my left leg with a dull ache. I've felt this for a month now and also discovered a small rise on my left hip, unsure if it's a lump or not but  soon after followed some trouble with my bowel movement. One week I had constipation the next Diarrhea, currently on week 3 of my disrupted bowel movement with mild Diarrhea. I'm due an appointment on Monday to do some test with my gp and I'm quite scared. For the past month I've been guilty of googling all most every day and making myself believe I have certain cancer's and life threatening illness's, part of me has wondered maybe my bowel movement has been disrupted because of the anxiety and stress which I'm under 24/7 having just left school with no exams to do and all my hard work going down the drain has caused me to become a bit depressed but my brain won't let me think of anything but the worst!
