IV Steroids

Hi folks A quick question. I finished a 3 day course of iv steroids at hospital on Thursday afternoon. Today I feel really unwell. My ms symptoms have come back as bad as ever with poor balance, eye problems and weakness in my legs. I am so tired today, feel shaky and just generally under the weather. I suppose I was hoping to take on the world. I was told it would take around 7 days for the steroids to get into the system. Has anyone else had a similar experience. I was diagnosed in feb and never had steroids before. Thank you xxx
