I'm not familiar with High Sensitivity CRP, I'm more familiar with ordinary CRP, but since yours is over the range it might indicate inflammation is occurring somewhere in the body.
Common causes of inflammation are :
1) Lung problems such as asthma, bronchitis, and COPD.
2) Arthritis of various kinds
3) Gut problems such as gluten intolerance, lactose intolerance, Crohn's Disease, Ulcerative Colitis, Coeliac Disease. You might have low stomach acid. Do you take acid-reducing meds or antacids?
Unless you already know you have an issue with 1 or 2 above, I would suspect gut issues first because they are most common.
The high CRP and your high reverse T3 are both probably caused by inflammation.
I would suggest for the moment that you :
a) Don't exercise furiously because that will reduce your Free T3, and yours is already quite low in range, plus it may increase your Reverse T3. Stick to gentle walking, swimming, yoga.
b) Get all your nutrients optimised.
Your ferritin is fine and you don't need iron supplements.
For your B12, folate and vitamin D, and co-factors magnesium and vitamin K2, follow SeasideSusie's advice on this thread :
c) Don't eat a calorie-restricted diet - it reduces your body's ability to convert T4 to T3 - and low Free T3 makes people feel hypothyroid and increases the chance of them putting on weight.
d) Switch to a low carb, high fat diet. A very good one which is not extreme and is free - you only have to register - is this one :
It's been developed for people with diabetes, but is just as healthy for non-diabetics.
These sites are worth reading too, but cost money for full access :
e) Although I have only read a tiny part of it myself, you may find this book of interest even though you don't have Hashi's - it gets good reviews anyway :
I would say that you should buy the book only if the other things I've mentioned don't help.
