My opinion of your illnessBIMA-arterial leak with Sero-hematoma with infection.-associated cellulitis would cause pain on touch.-Advise-You should consult the concerned cardio-surgeon who would do MRI and would plan for its decompression and control.-Hope this would help you to recover from worry-some query.
