I had IV steroids in hospital four years ago and on the fourth day they sent me home to cope alone. I was walking again (just) and had to fend for myself. While I was taking the steroids I felt high and couldn’t sleep. When I got home all I could do was sleep and I felt really down and weepy. Worst of all, with IV steroids they don’t give you the leaflet with side effects so you don’t understand what is happening.
I found it took at least a week before I started to feel a bit like me again but I was still very tired from the relapse. I’m sorry, but I don’t know how long it will take before you feel better. I’m sure the heat won’t be helping either.
I had oral steroids earlier this year and they reacted much the same but at least I knew what would happen this time.
All I can say is rest as much as possible and remember that things will get better eventually.
