Hi everyone,I'm in the US. I have good insurance but I have seen primary, endocrinologist,and metabolic weight Dr. They will not do anything for me, wondering if it's worth it to pay to see a functional medicine doctor? Have tested TSH every month,1.8,2.9,5.1,2.8,and 3.0. I feel I have every symptom,cold,tired,can't lose weight,sore,hair loss,last 1/3 of eyebrows have disappeared. I also have fibromyalgia and know some of my symptoms can be related to that too. What do you think?
