Sudden regression after months of treatment

Hello,
I am sorry this is a bit of a story, but I have no where else to turn.

Background
I am a 34 year old male, healthy(Other than Lyme) and active. 6 months ago I was diagnosed in both the USA and Germany as having Lyme. I started antibiotic treatments, rotating in/out different antibiotics, often taking 2 at once. Amoxicillin, Azithromycin, Doxycyclin, Minocycline, and Rifampin are the ones I can remember. In addition, I started taking Serrapeptace, Samento, Chlorella, CBD oil(No THC), and vitamins. I was doing great. Working lots, lightly hitting the gym again and I was probably symptom free 4-5 days a week, with minor symptoms other days.

The Hike
A couple friends and I went on a fairly easy, but long hike. about 9km in, one of my friends fell and hurt his leg so we basically had to carry him back to the vehicle. It was absolutely exhausting, we were all sweaty, dehydrated messes, but that night I felt ok. The next day was a disaster. I was more Lymey than I had been in 6 months. 2 days later I went to my doctor and she took me off Rifampin, kept me on Minocycline, and put me on Cephalexin. My world crashed. Every day around noon, I felt EXTREMELY Lymey, Herx'y and basically I felt waisted drunk, with an extremely sore neck. It was as sick as I can ever explain and was basically bed ridden for 4 days. I called my doctor and she immediately took me off Cephalexin. I started to feel a little bit better and we decided it would be a good time to try IV Ceftriaxone. The plan was to do 6-8 weeks worth of IV, 3 days in a row each week. After three days of the IV, each day I started to feel worse. By day 3 I was quite lymey again. Its been 4 days since I had my last IV and I have more Neurological issues than I can handle. I was supposed to start taking Tinidazole on my no-injection days, but my doctor told me to hold off until we figure this out.

Todays Status(13 days after the Hike)
I took Minocycline, CBD(No THC), Zeolite, Chlorella, and vitamins. I feel like my brain is too big for my skull. Constant headache, dizzy, sleepy, nauseous, brain fog, sensitive to sound/light and sore neck.

What happened to make me regress so badly and what can I do? I am starting to panic. What could the hike have done to regress my progress like this? I am open to any suggestions because I cant go on like this.

I'd agree that your body made it clear you needed to scale back.

Have you done blood work to verify that your kidneys, liver, and adrenals are handling your treatment ok? I've had to scale back my treatment a few times to let my body readjust.

Regardless of the why-when I was at the six month mark I hit a wall and felt like I back tracked. I panicked and felt devastated until I read an article about one of the pseudo celebrities with Lyme who had the same thing happen. Since then I have seen this question come up a half dozen times. I have no answer as to why this happens. I can only tell you that it's relatively common and once you are back on track you should see another large reduction in symptoms.

Jesse -What about your Bun/Creatinine, eGFR, ALt, and AST. The first two are kidney function, second two are Liver. Both are tested on a complete CBC panel.

Our adrenals and thyroid are stressed. It's wise to have those tested. If your Dr orders a Thyroid test make sure it's the free T3 and T4 test.

Tindamax-generic is tindizol works great in combination with a lot of other abx's. It's always given in some form of a pulse. I've seen anything from 3 days on, 4 days off to 3 weeks on 3 weeks off.

If you were making good progress with your Dr then I would continue to trust.

I hit a wall at 6 months too, but in my case I don't think it was a regression. From what I've experienced I think the body will attack Lyme in phases. The next phase typically starts when you're feeling amazing and have tons of energy and your body decides to channel that energy into peeling back another layer of the disease. If you look into the alternative medicine world they call it a "Healing Crisis" and it usually starts when you feel great and have alot of energy. In reality our immune systems and detox organs are really doing the bulk of the heavy lifting in helping us heal rather than the medications or herbs.

I think relapses can be real as well, and so it can be hard to tell whether you're making progress and working to clear a deeper layer of the illness or just relapsing. But just because you feel worse doesn't necessarily mean you're in a worse state than you were before, with this illness feeling worse often means getting better. Depending on how long you'd had untreated Lyme for, feeling great with only 6 months of treatment is probably due to only having scratched the surface of the infection rather than have truly eradicated it.
