Macrobid and leg pain

I started Macrobid last Tuesday coupled with Perks for the pain. I have finished the few days of perks that I was given and have started noticing severe leg pain and insomnia ( I cannot sleep due to extreme body pain and sweating.) along with sharp pains in my stomach and very loose stools. Im calling my Pharmacist tomorrow to see what he says. After reading what everyone else wrote, Im starting to get scared.

Took it for 5 1/2 days threw the rest away.
Having EXTREME nausea, headaches,flushing, horrible leg pain,stomach fluttering.
I feel overall sluggish and flu like. I would rather have the UTI , I feel WORSE since taking the medication so I discontinued and hope that I dont end up like some of the other people I've read about who had effects for up to a year!!!
