Following an asthma attack which landed me in hospital for a few days, I was told to take 8 puffs of symbicort daily for three months, before reducing. I reduced to 6 puffs daily successfully, but when down to 4 my chest started tingling etc. This could have been due to a cold that was so slight I wasn't 100% sure I had one. I was advised to go up to 6 again for another 4-6 weeks. Today I have started 4 puffs daily again. My question is how soon could the effect of reduced steroids show up? My common sense tells me a few days, but what is the general experience? I am new to this and so have no idea how my body is likely to react.
