A couple of weeks ago I noticed a tender spot under my right nipple,I figured I'd bumped myself and paid it no more attention.this week I noticed the tenderness had moved downward across my ribs. After showing my girlfriend,she noticed that when I stretched my arm up you could see a raised bumpy line from the top of my ribs heading towards my stomach. This has me greatly concerned and I can't see my gp for a week. Should I be seeking help sooner??
