PredniSONE and tip of the iceberg

Hi I am a 44 year old asthma patient. I have had asthma since the age 2 and have been on & off prednisone since that time. As a child until age 20 I was on predinsone daily. My question is has anyone experienced nerve problems due to long time use? I do have muscle weakness and spasms, but I am interested in if anyone has had nerve problems. Please email me at ****** and refer to prednisone.

I had been on a prednisone dose pack (not too strong??) about a month ago for a neck injury to take away some inflammation. No side effects to mention and my neck felt tons better. Yesterday I went back to my dentist after 5 days of pain from a root canal. He put me on a prednisone dose pack saying there was some inflammation in the bone, very common, and the prednisone should take care of it. I took my dose yesterday, didn't sleep well (common side effect it seems) but then today my heart is racing and feels like it skips a beat. I have read this happening to folks on much higher doses, anyone have this kind of side effect with 20 mg/day?
