<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, may I answer your health queries right now ? Please type your query here...There is an inch long lump on the left side of my pubis. I doubt it is anything but I suspect a swollen gland. Do I need to see a doctor or just wait. It has been there about 2 days. Showed up after a 10 mile bike ride - first bike ride in 9 years.  <response>: Welcome to Chat Doctor .1. The possible cause will be lymph nodal enlargement. Lymph nodal enlargement will be seen after any infection inflammation.2. The excessive stress the thigh muscle have experienced after the bike ride after a long time - may give lymph nodal enlargement due to localized stress.3. If any other underlying medical condition you are experiencing - treat the cause first.4. If lumps persists without any pathology - an ultrasound examination of the lump - will help to analyze the nature of the lump, its source and extensions.5. Depending on findings a needle sample might be necessary. Ant treatment depending on findings. Good luck. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
