vaccine side effect?

Emily • Nursing student 💉 💊
I got the meningococcal B vaccine on Thursday October 6th and have had pain in my arm ever since. The day after it was a bright red circle and today (10-11) there is a Knot/lump in my muscle and it's still pretty painful (even when I lift my arm to turn my steering wheel). 
My mom is a nurse and she always says it's fine. I am in nursing school too, but anyone else have thoughts on it? Anyone have the same reaction? 
Thank you!
