Ice Cream Shoulder

Could either be a referred pain from a nerve (trigeminal or perhaps mandibular). The nerve in your jaw could be referring the pain el;sewhere. Though there is no direct branching from jaw down through shoulder. Maybe you're just weirdly wired!?

In electro-physics that could mean that there's crosstalk between nerves but I'm so out of my depth here it's not even funny. Good question for your Physician.

Well, Ragman, if the choice is between a trigeminal nerve and being weirdly wired, I've a feeling it's the latter.

Mind you, other people I know have had the same pain. So perhaps I attract other disfunctionally wired people.

Perhaps that's where giving someone the cold shoulder comes from?

Does any one particular flavour cause the pain?
