Hi,Dear thanks for the query to HCM virtual Clinic. I studied your query in all the details put forth by you. I understood your health concerns. My replies are as follows- The problem of lump below the breast with bruise over it needs more information-As to how long this lump was there?How long is the bruise over the lump?if it hurts on pressure?Any recent fever/or viral infection ? Cause of the health problems you queried- In the given situation,when the pediatrician has examined and has ordered X-ray and blood test,I would advise expert opinion from ER Surgeon,who would rule out many other reasons for such a pea-sized lump. As I don t have any photograph of the lump or any direct examination data,its very difficult why your doctor advised x-ray and blood tests. You should wait for the reports and to plan treatment from your pediatrician on the lines suggested to you and get second opinion from ER Surgeon doctor. Hope this would resolve your query with full satisfaction. Welcome for any further query in this regard to ME by direct question at HCM. Write excellent review and hit thanks, to narrate your experience ,which would improve my rating for many other visitor s to HCM. Wishing you fast recovery. Have a good day. Dr.Savaskar M.N.
