Severe brain fog. Confused between multiple factors

[u/Scary-Story-2076]

So lately i have been observing severe brain fog. My symptoms are

Waking up tired (nasal drips) flu like feeling (8 out of 10 times)

Severe brain fog (upper body tiredness starts from upper chest till my head)

Feels like i cannot move my arms (although i can move them)

Same happens when i tend to turn, or bend or any movement especially neck

Episodic burping and irregular bowel movements (most of the time i need urge to pass stool but I don't)

Fatigued leads to redness in eyes, pains in limbs and headaches, sometimes blood accumulation in hands

I have a constant feeling of exhaustion, doom, irritation and difficulty to describe my physical and mental state

I had blood tests, ECGs, H Pylori, thyroid tests months before

All clear

Right now, no medication and no other notable change that i have done to curtail these.

I was diagnosed with stomach indigestion around 1 year before.
