<s>[INST] I have a back ache in my upper left back just below shoulder blade. Had my heart test, urine tested, cat scan which showed all fine except I have diverticulitis which I already knew. Where should I go next to see what s causing this. Pain makes it hard to sleep. It s dull like a tooth ache. [/INST] Dear sirHello This pain shows overexertion.You can take Arnica 200 and Ruta 200.it will give you relief. </s>
