Using a throwaway because Im scared of my judgement lol.

My girlfriend has had an issue with her neck since we started dating. She calls it a "neck pop" where if she moves the wrong way, she'll tweak a muscle. I dont doubt she has a problem, she goes to a physical therapist for it and apparently she told my girlfriend that itll never fully go away.

The thing that bothers me is that whenever it happens, she make this loud gasp/moan sound, even if we're out in public. Then she asks me to rub it for her, regardless of where we are or what were doing. Its like shes milking it for attention. 

Yesterday I got fed up with it. We were at the mall and suddenly she basically shrieked and sat down on a bench with her head sideways and asked me to rub her neck. People were staring and I told her to rub it herself and get up and stop being dramatic, and she started crying and told me I have stronger hands than her. I walked away and left her on the bench.

So, I ask you all, am I the asshole here?
