Hi! I have had this lump in my abdomen for a couple of months now with no pain, I had an ultrasound and she said it looks like a lymph node at a little over 2cm.  Another gritty feeling lump was found in my groin area... Is this something that will involve more test an something to be worried about?
HI. The lymph nodes enlarged at such sites must be evaluated as there may be a primary reason. Request your Doctor that you want further investigation and particularly FNAC, that is fine needle aspiration cytology to get the exact diagnosis. If need be you can go for excision biopsy.
