Thanks for your query. Read and understood your concerns about pain in the abdomen left side of the abdomen. Veins have become thinner and the right side of the collar bone has become swollen. Also noted that your doctor thinks that you have IBS. For such a problem to be said as IBS, you need to undergo all relevant investigations to be absolutely normal. These are the routine tests of blood, urine, stool, Colonoscopy and CT scan of the abdomen. So get the above investigations and get treated as per the findings. </s>
