Hello again, I have another question from a recent blood test. My plasma C reactive protein is 8 mg/L (normal range 0-4) (as well a slightly high potassium which I posted about earlier). My GP is not concerned, but having read up I see that it could be a sign of a badly managed autoimmune disease like rheumatoid arthritis or lupus. I do of course already have Hashimoto's, so I worry that I might be developing another thing... what would the best course of action be? Do an auto immune profile?
I feel reasonably well though have noticed some stiffness and pain in my finger joints and sciatica-like pain from my buttocks down to my legs (alternating) and sometimes neck over the last weeks, plus since a few days a slight tremor in my left arm.... I was planning to sit back and see if things go away over the next few weeks before going to see the doctor about these symptoms.
Background: I am on a combination therapy of 125mcg Levothyroxine and 15mcg Liothyronine daily, fully gluten free, all vitamins/minerals at good levels (I supplement). TSH is undetectable, FT3 5.3 (3.10-6.80pmol/L), FT4 18.8 (10-23 pmol/L).
Thanks for any thoughts!
