Since last few months, I have a lump on chest  and it's pressing my esophagus which I feel when I feel difficulty in swallowing food sometimes. The lump feels just under the skin and possibly on middle chest bone at bottom of chest. The lump is around 1 inch in diameter and it's soft and moving and not painful, so my guess is it could be Lipoma as I already have many Lipoma lumps on my arms & thighs without any problems. I am yet to visit a doctor personally due to Covid reasons. I hope it's a benign & non-cancerous tumor. Any advice or suggestions?
