Went for a folowup with my ortho surgeon for spinal fusion and was still having issues with SI joints so he gave me a ccrtison shot for both sides. It's was on Friday and over the weekend I developed these symptoms - nausea, no appetite, weak/extreme fatigue, shaky/agitation, lightheaded, hot flashes/cold chills, depression. How long does it take for these shots to leave your system. I can't even go to work and even do normal daily task. As well as all of the other symptoms I get very winded walking short distances. How long till the shots get out of my system
