Thanks be to god symptoms and conditions

I was prescribed Leavaquin for pneumonia - 500mgs for 5 days. Have taken it in the past for pneumonia with no observable side effect except the dry mouth. However, this time, I have nausea, diarrhea, excruciating pains in my feet going up to both knees, (despite using lidocaine patches for neuropathy) insomnia, headache, stuffed up nose 3 hours after ingesting it. Additionally, I feel "down", lethargic, lack of clarity in thinking. I am stopping the Levaquin today, the last day. Thanks be to God for this website. I can see that others are suffering the same side effects.
