Good morning , for the last 7 days i have had an annoying muscular pain on my left shoulder and an annying swallowing sensation . i have been to my gp but cannot have blood tests until Tuesday , they want to rule out anything sinnister which has worried me now, I have done the wrong thing and have been googling . Is it common to have a pain in the shoulder with lung cancer? it is only sore when awake when i lie down it doesnt appear to be sore.
