Hi Dr I Have A Lump On My Solar Plexus

Hi Dr I have a lump on my solar plexus it developed during a period of great personal emotional trauma, the death of my mother then followed by a very nasty relationship break up. I am being treated for Hep C, the virus is now gone and I have my final follow up in a couple of months time. The lump however despite 2 doctors telling me it's nothing is getting quite uncomfortable not growing but it feels wrong.
