Hi strangely I had similar symptoms and saw the GP today who said that I must have a sore rib. I'm concerned because I can feel a lump in the side of my breast too, and it feels slightly warmer than the other. 

My plan is to leave it a week or so and go back to see a different doctor if it persists. 

I had suspected Covid a month ago and had severe chest pain with it so not sure if it's all related - have you had any similar symptoms recently?

i havent been suspected of having covid 

but i was cleaning the other day washing the floors and then the nect norning it felt sore and when i felt around theres a lump.

i went docs he felt it and said nothing to worry about but its still worrying me especially because i am type 2 diabetic . like you ill wait a week and then go docs agaun. im scared its something to do with liver cancer or gallbladder 

Hi. Did you ever get a diagnosis for this? I've got the same thing, hard lump under right rib which is tender when touched. I'm waiting for bloods to come back and to get a lump checked for skin cancer so I'm beside myself with worry that it's liver cancer.
