Solu-Medrol and heart palpatations

I started on IV Solu-medrol this past Monday for an MS exacerbation. I was on it for five days. Yesterday was the fifth day.

I have had trouble sleeping, heart palpatations and today my face is very bloated and all flushed. The biggest thing I feel is that I am really out of it and feel really tired, but can't sleep. I hope these treatments are worth it and slow down the exacerbation. I went from 4 to 14 lesions in six months and have a new one on my brainstem. I am also on copaxone, so that could be causing the heart palpatations too.

On IV SoluMedrol for 3 days. Have RRMS and was having leg weakness and problems with vision. Steroids caused horrible heart palpatations and shortness of breath, along with nausea and facial swelling, and and increase in temp and facial flushing. Is this normal??
