I am 59 years of age, and I am, and have been having this dull but 'very present' pains in my left arm pit, all day long and sometimes it radiates down my left arm and tingles in my fingers. I obviously do not have the amout of medical knowledge to analyze what is happening, but I do not have money to offer on here for any services anyone offers to me. Please, know this ahead of time to save us the hassle.)
