Its best to let the doctor know so that they can advise you from there but apparently the shoulder tip pain usually happens after the tube has ruptured and is a sign of internal bleeding, in this case, you would be in alot of pain so try not to panic. I have had aches in my neck and shoulders but think it was from sleeping odd. I did have a scan to check for ectopic, unrelated to those aches and its not. Like I say, best to speak to your gp cos if anything it may just put your mind at rest x
