Plegridy and knee pain?!?

Hi, I’ve just started Plegridy (began in January and built up to full dose now) and I’ve noticed injection site reactions which is annoying but I was expecting. I’ve also noticed quite severe pains in my knees at times. It seems like it might be linked to the Plegridy as it started shortly afterwards and has got worse which each dose but I can’t see it mentioned on the side effects. I’m due to see my MS team next week but I was wondering if anyone had experienced this before or had any advice. Thank you in advance
