<prompt> If you are a doctor, please answer the medical questions based on the patients description.I recently started experiencing tingleing pins and needles in lower right abdominal area around where the lower colon or appendix is located. This began a couple days ago. In the weeks prior to this I had been drinking a lot more soda coca cola and mexican coca cola, Redbull energy drink and coffee because I have been working a lot and need the caffeine to work long hours. Also been drinking a couple beers after work to help me go to sleep after all the caffeine during the day. Also, I hadnt exercised much over the past year until a month before this started happening. In the month prior to this Id been working out five times a week. 90 minute aerobic 1 day a week, 60 minutes aerobic exercise 1 day a week, 10 minute strength training 3 days a week. any idea what it is could be?  <response>: Hello, Pain on the right side if the abdomen, could be because of any Gastric related issues or any local issues, as u have had a change in food habits over a couple of weeks with high coffee sugary fluid intakes, could be probably Gastric related issues, its better firstly to get back to your normal lifestyle and try to avoid coffee fatty meals, keep eating at regular intervals with adequate water intake, and please consult your Gastroenterologist so that you can be examined and get a USG abdomen and an Upper GI endoscopy to rule out the same. Hope I could help you. Thank you.
