Good morning , I've been diagnosed with fibromyalgia, hyper mobility and sacroiliac joint disorder. I primarily suffer with severe joint pain ( I use a walking stick or crutches) exhaustion headaches lIBS and more. I take a combination of tramadol paracetamol codeine and duloxitaine to function . My tongue has a scalloped edge , and has done for some time. I had a thyroid function test done 7/8 years ago and was told I was at the lower end of normal levels. Do you think it's worth using for more blood tests ?
