@Ed209 - I developed huge lumps in my legs in 1991 (erythema-nodosum) together with shortness of breath, and was prescribed prednisolone.
I refused to take it.
My GP said "I suspect you have sarcoidosis and you are so wrong to refuse it.
Within a week you will come here and plead for it."
Within three days I felt incredibly ill.
I went out to walk my dogs - luckily my wife was with me. I could not breath, could not get back.
She got the car, and phoned my doc.
He said "don't wait for an ambulance - go straight to hospital."
She got me there - they injected steroids - gave my an X-ray - my lungs were completely white.
I had sarcoidosis and hypercalcemia.
Blood calcium levels are critical at 2.4 /2.5 %.
Mine was 3.3 %.
I was hospitalised for two weeks and prescribed prednisolone at 30mg a day for six months.
Sarcoidosis can easily kill you.
When calcium becomes mobile in the blood stream it can destroy lungs, kidneys, eyes, anywhere there are tiny capillaries.
It forms a sediment. I was very lucky.
To cut a long story short - I got better, having lost just 1cm off of one of my kidneys.
The specialist said "MrHewett - you were well into your last day on this earth."
So, prednisolone undoubtedly saved my life.
The downside is, in 6 months I had absorbed over 5,000 mg of prednisolone
My Tinnitus (albeit at low level) started a few months later.
But I'm still here - and I tend to listen to my doctor a bit better these days.
Sorry this story is so long.
