<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi, i have found a lump in my stomach about the size of a pea, its located under my navel slightly to the right. It dosnt hurt but im worried as 2 months ago i had a swelling near the top of my leg on my pantyline which the doctor thought was a cyst which has gone of its own accord, took about 4 weeks to vanisChatDoctorpletely!  <response>: Hello! Welcome to Chat Doctor. This lump near navel can be a lipoma or hernia. If there is an impulse in the swelling on coughing then it is more likely a hernia. Do you have chronic cough constipation straining at urination? Local examination by your doctor is necessary. There seems no connection between cyst on thigh this lump. Ultrasound can confirm the diagnosis. Hope this information is useful. Thanks. Regards.
