Amos Tin

I can feel a lump at the junction of my sternum and left T2 and feel pain, when I press it gently. I think it must be the thymas gland.

When I am pressing left my surretus anterior from my shoulder down to about T3 or 4, I can also feel the pain.

This is the second time that the lump appears, since the last 3 months. The first time lasted for about 1 week, before it subsided.

Any advice would be very much appreciated.
