Hi guys,

I'm 21 and I have had some worrisome symptoms for about 3 weeks now and need some advice

Having took up an office job in July, I noticed that I was getting very bad burning like cramps down my abdomen. During that time I had blood WITH my stools. Went to A&E, doctor said it was fine - blood/urine fine. However, I've also had constipation and accompanying lower back pain when I bend foward, which has now gone.

However over the past 2 weeks, I've often been getting a tight straining like sensation across my left abdomen, where it constantly feels tight. And very recently, I've been having quite bad indigestion, where it feels that there is something lodged in my oesophogus.

I have to admit however my lifestyle is pretty bad - I have barely exercised since June, and am often slouched sitting down, and my diet is pretty poor too.
