I have been diagnosed as having fibromyalgia & osteoarthritis of my knees and ankles. I also have hashimotos,s and have recently become gluten intolerant after having loads of stomach problems. What I would like to find out is the pain and weakness in my legs down to fibro or arthritis? After a full on weekend trying to catch up on things in my small garden I have to virtually crawl upstairs as my legs are so painful ,stiff and weak. I had a very bad night last night shivering and sweating at the same time & have been plagued with stress headaches ( I take bp meds) can any one make any sense of this? Thankyou so much for reading this.
