Have been on pred for 4 weeks now down to 12mg since starting the pred I'm gradually feeling so much worse Breathing and so much pain in my right upper back around right rib cage area, upper back and shoulder. I take it in the morning and with in an hour I feel good but by mid afternoon I start to feel worse again. Do they work like that? Could pred make symptoms worse? ( no diagnosis of yet) resp spieacist said sensitivity pneumonitis but I'm not convinced. Another ct scan in Jan.
