Hi, I woke yesterday morning with a lump lodged on the top side wall and inside my bellybutton that is tender (sore) to the touch. It is about the size of a pea. Could it be some kind of and infection or something else. I have no other symtoms and am extremely always healthy so this is really bothering me.
Hi, I understand your concern.  -A painful pea sized lump on side wall of umbilicus, may be a painful/ inflamed lymph node, that has arisen because of injury/infection.  - A simple lipoma (which is usually painless) being irritated /infected by itching, massaging, pressing, pricking-may turn painful.  - The painful lump can be beginning of an umbilical hernia. Here the lump grows on stress/coughing etc. A course of antibiotics & anti-inflammatory Chat Doctor.  But if it does not subside/increases in size/ affected by coughing, you should consult a surgeon for exclusion/treatment of hernia.  Thanks.
