I am seventy- three years oId, recently I was prescribed prednisone plus a basic pain medication, and I haven't felt this good in years. My joint pain was gone my allergies were better; I felt twenty tears younger. My question is, if this medication is prescribed for mild joint pain, what ever the dosage, how long would it take before the unfavorable side affects would manifest themselves? Even if it killed me at eighty years of age what difference would it make if one felt good up to that point?
