hello my partner has had deep pain in his ribs, pushing into his back and round the sides of his body and now he has multiple small lumps, which are not visible on the skin but can be felt when pressing on the skin. they move when touched, has little appetite and is in constant pain. i am terrified about this, he has had blood work done and ekg which has came back clear. his main pain relief is heat including a hot shower or a water bottle. if anyone could give any guidenace it would be really appreciated as i am terrified. thank you
