I just started a fast food job last week and since I’m still training I’m usually only working 4 to 5 hours a day. I worked today and now I’m in a lot of pain. My knees and ankles are hurting so bad to the point where they feel like they’ll give out. I am seeing a doctor because I’ve been having the pain and other things going on and the doctors think I may have am autoimmune disorder. I was wondering if this is an effect of it and what I needed to do so that way I’m not struggling to walk every time I work.
