Sternum tip hard - No Pain at all. Pain!

When I take my stomach inside and touched I am feeling hardness exactly at end of sternum it's also called xyphoid process i think. I don't see any pain when touched and pressed. I don't have any kind of fever .. or cough or it won't pain when coughed. After eating I feel fullness and some kind of discomfort which I never experienced.. my stomach feel light in morning but after eating it gets discomfort.. I contacted General Surgen they suggested one month medicine…sternum hard they told it is normal.. but I never experienced this kind of discomfort. so I am not sure why sternum tip is hard ...kindly suggest or guide me please Per doctor I took micaine gel 3 days .. I see no stomach discomfort however sternum tip is hard with zero pain
