Sore eyes

Good morning. Bit of a weird one - but that’s MS!!! Sometimes when I inject 44 rebif I get the painful miserable side effect of sore eyes. It’s not ON like. Just painful - reading or watching TV doesn’t make it any worse. Treatment is codeine and ibuprofen. Which seems a bit weird to me as they are not neuro whatsit - sorry that word escapes me. Does anyone else get this and if so how do you cope? Thank you in advance wonderful friends Hugs Min xx
