I am a 32 year old female, 5feet 5.5 in talls. I have a lump in the center of chest about 1 in. below the breast line.  It measures approximately 1in by 1in and is visable if I am lying down.  It is not tender to the touch however I have be feeling a sense of fullness in the area, along with discomfort and some dull pain.  I do not know how long it has been there I just discovered it about a month ago when I was feeling uncomfortable in the area.  I do seem to get a strange feeling when I run or do any exercise.  Past medical history of left ACL reconstruction and a compression injury to lower back 16 years ago.  Should I be worried?
Hi, Dear,Thanks for the query to Chat Doctor. I studied your problem in depth and I understood your concerns. Cause and plan of Treatment-In my opinion on the given data, you seem to have xyphoidalgia-painful typhoid bone just below the breast line, just down in the center of chest. You just have a fullness in the area and no lump even on lying down, but is painful on pressure, with dull ache pain. I would advise you to Consult ER Surgeon, who would treat it with anti-inflammatory x 5 days time / or with Voltaren(OTC)gel locally for 5 days time to control the pain. This would resolve your painful lump issue. Plz check out with your ER Surgeon who would treat it accordingly. So don't build up wrong concepts and self-medicate your self which would increase risks and costs to you.Instead, just ask a query to Chat Doctor and be comfortable to resolve your health issues.
