I was prescribed 20mg 3x daily for five days to treat "Reactive Airway Disease/Bronchitis." Yesterday was my 5th and final day of taking the medication and I noticed both of my shins began hurting for no apparent reason when I walked. I didn't think it had anything to do with Prednisone. Then, last night, I suddenly felt weak as if my blood sugar had dropped tremendously and ate a grapefruit while trembling with weakness to stop this feeling. Again, I made no association with this and Prednisone. Last night as well, I noticed that my shoulders suddenly became achey on both sides of my backbone for no apparent reason. This morning, I woke up and the pain from my shoulders had spread to my hips and the entire area between my shoulders and hips is tender to the touch. Today, after not taking any of the medication, I feel mentally blurry, have moments of what feels to be low blood sugar and flu-like symptoms. I'm also still experiencing the muscle pain in my back and hips although my shins seem better. My pharmacist told me to call my Dr. and seemed surprised to learn I was not weaned off this medication. All of the symptoms I have described above are side-effects that should be reported to a Dr. immediately, according to my pharmacist. Another less-serious side-effect that began yesterday is swelling in my feet, hands, stomach and face. I also had diarrhea today.
