@morganjane There are a couple of things that come to mind. In your history are there bodily injuries (such as a whiplash?) or exposure to foreign materials in your body, perhaps extensive dental work? I ask because surgical implants are made of foreign materials and root canals contain toxic substances and I've been down that road myself and I know that removing my old toxic dental work improved my health a lot. I had also fractured my ankle recently, and the titanium fixation plates were causing pain and hives. I had them removed and my health and asthma improved. Are you exposed to mold where you live or work? That can cause health issues. Do you spend time outdoors? Some of your symptoms are common with Lyme disease and the many co-infections that are associated with a tick bite. Tick bites don't always cause the expected "bullseye" rash and a bite can easily be missed. Did you ever have a high fever that was unexplained?

I have had thyroid nodules for years, and had Hashimoto's thyroiditis which is an autoimmune thyroid condition. That was likely caused by the 50 year old silver amalgam dental fillings according to my environmental medicine doctor. My blood work was off the charts for the antibodies against my thyroid, and now after several years and after removing all the metals from my body, my blood work is now in normal range and no longer indicates Hashimoto's. The thyroid is very sensitive to toxic substances. Not everyone reacts to metal surgical plates, but I also became allergic to metals in pierced earrings no matter what I tried. I did also notice your tattoos, and tattoo ink has been written about in medical literature for toxicity.

Mainstream medicine may not look for a cause for these kinds of things. I found that my functional medicine and environmental medicine doctors were helpful for this, and they also optimize female hormones. There can be different reasons for thyroid nodules. I had multiple nodules associated with Hashimoto's and over time they shrank as I got better. My doctor said a single nodule is more of a concern for a suspected cancer. I did have a needle biopsy of the largest nodule which is a simple procedure and cancer was ruled out. I think it was an ear nose throat doctor who performed the procedure. An environmental medicine doctor can also advise the patient to see other specialists and recommend what specialties would be considered.

Here are some links with information about environmental medicine and Lyme disease. Lyme is misunderstood and it is hard to find a specialist who understands how to cure it if it is chronic.

In this discussion, "Lyme Disease and Neuropathy", you'll find a discussion and this comment has some specific information:

Environmental Medicine
They can be allergy specialists and look at the functional chemistry in the body and optimize health. Here is a provider finder.

I have a current doctor who is also an allergy specialist in functional medicine who is in the Forum Health Group https://forumhealth.com/ They have doctors nationwide.

Typically these doctors look for a cause of a problem instead of prescribing something to treat an effect or symptoms of a problem. They may not be able to address all of your issues, but they may be able to help with some of it that is allergy or immune related.

There is also the practice that started this field of medicine. That is the Environmental Medicine Center Dallas in Texas. Here is there website. https://www.ehcd.com/ There is information at this website about issues they can treat.

Perhaps some of these other avenues could help lead to an answer for you. It will likely take some time, perhaps years to trace the issues and find the source. You'll have to advocate for yourself. I didn't have answers for years on some of my issues, but it was worth it to keep searching. I have lots of seasonal allergies as well as sensitivities to chemicals, fragrances, and I react to mold exposure with asthma. I learned a lot of this just in my experience of what worked and how my health was improved. Even though my thyroid is better now, I still need to take thyroid medication because damage was done and my thyroid can't produce enough of what my body needs. My functional medicine doctor looks at thyroid function differently than a main stream medicine doctor who tends to look at "average" blood readings based on entire populations where many people in that average have thyroid hormone levels that are low.
