Hay Fever

Hi All, Think I’ve had mild hay fever the last couple of days…not like a cold ,just a runny nose to slightly bunged up. Question is(as I didn’t get it last year) will it increase the spasticity in my legs …as by 4pm this afternoon they were STIFF, to say the least. Have been feeling much better with other symptoms up to now, which I was hoping was down to 3 months on Tysabri. Thanks All Libby x
