I was prescribed Prednisone for only 5 days- my doc said to take it to rule out inflamed sinuses as a cause of my dizzy/lightheaded symptoms. Well, this medication did everything but take away my dizziness. On my 2nd night I was feeling anxious and had difficulty falling asleep. On my 3rd night, the it got worse. On the 4th night, I felt like something was crawling under my skin- it was so uncomfortable- I kept rubbing my arms and paced back and forth until the feeling went away about 2 hours later. On the last night, I woke up from a nap feeling tender all over- my ribcage, my shoulders, under my arms, my neck, jaw. My jaw even appeared to be swelled. My body was so sensitive to touch that I couldn't even carry my purse on my shoulder the next day as I walked to a doctor's appointment. My doc told me that the tenderness was probably due to a virus that the Prednisone had initially supressed. What do you think? Anybody else ever had these side effects or effects after completion of the Prednisone? Oh and about the dizziness, it just got worse. I will never take this medication again.
