question: I slipped on ice and fell on my back. Now I feel weak and slightly feverish. My chest and my ribs and everything under my ribs hurt. Not to mention all the muscles in my back. I took two 200mg tablets of ibuprofen. I also have 10 mg tablets of cyclobenzaprine from an old back injury. I usually only take a quarter to a third of a pill because I am so sensitive to drugs. I am 5 6 , about 150 pounds and in good health. I have struggled with back for many years but it has been exceptionally soar the past week and today I fell. Is it safe to take the cyclobenzaprine now? Should I apply heat or ice? Is it normal to feel weak and dizzy after a fall if I didn t hit my head?
