<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor. My name is Eduardo and I have had an abdominal workout routine thats pretty intense for a couple of months now and most times after a good workout I will have pain on my lower right abdominal. Pain increases as I do more exercise such as soccer the next day. Its not unbearable, but enough for me to stop. Im worried it might be my appendix. What do you think?  <response>: Hi, Usually one gets used to the stress after physical exercises within 4-5 days so muscular pain vanishes after that, if you are regular in exercises. You have pain at a particular part of abdomen after long days work out. This suggests some inflammation inside-may it be an appendix intestine Cecum bladderureter ovaryin female. Its advisable to exclude it by Abdominal ultra sonography. Thanks.
