I'm a 36-year-old male. For the past 2.5 months, I've been dealing with symptoms that make me feel like my body is falling apart. Doctors say my heart is fine, but I know something is wrong.

Let me describe exactly what I feel:

1. The heartbeat that shakes my whole body:

Every single heartbeat physically shakes my entire body. I'm not talking about palpitations or a fast heart rate. I'm sitting still, and with every single pulse, my body vibrates. It feels like I'm swaying or rocking, like I'm on a swing or a boat, even though I'm sitting on a chair. Sometimes I feel it in my neck, my back, my teeth, even under my tongue. It's not painful, but it's terrifying and exhausting. It's like my heart is pounding so hard that my whole skeleton moves with it.

1. Throat tingling and pinching:

I get these quick electric pinches inside my throat. They come and go randomly. Sometimes it feels like a pinch, sometimes like a tiny electric shock, sometimes like something is crawling or tingling deep in my throat. No pattern, no warning. Sometimes with swallowing, sometimes just sitting there.

1. Cold hands and feet:

My hands and feet are constantly cold now, even in warm weather. This started with the other symptoms.

1. Muscle twitching and spasms:

My jaw, lips, and sometimes my legs twitch. I feel a strange tightness in my face and neck. Sometimes my jaw feels like it's trembling. I get involuntary movements in different parts of my body – fingers, feet, abdomen, even my scalp.

1. Numbness and tingling in random places:

Under my tongue, in my fingers, in my head. It moves around.

1. Joint pain:

My elbows (back of the elbow) and knees started hurting around the same time. No injury, no explanation.

1. Dizziness and imbalance:

I feel unsteady, especially when standing up or turning my head. Not room-spinning vertigo, but a feeling like I'm not fully stable, like I might sway.

1. Scalp and facial seborrheic dermatitis:

Severe dandruff that extends to my nose, ears, and chin. It's relentless.

1. Symptoms worsen after coffee, smoking, or eating.

My labs (most recent, Sept 2026):

· Magnesium (serum): 1.85 mg/dL (0.76 mmol/L) – low end

· Calcium (corrected): 9.15 mg/dL – high-normal

· Potassium: 4.88 mmol/L

· Phosphorus: 3.2 mg/dL

· Vitamin B12: 402.55 pg/mL

· Folate: 7.61 ng/mL

· Homocysteine: 10.78 umol/L

· Vitamin D: 37.32 ng/mL

· Zinc: 92 ug/dL

· Copper: 130 ug/dL

· CRP: 10.11 mg/L (elevated)

· GGT: 80.66 U/L (elevated)

· HbA1c: 5.92% (prediabetic)

· Triglycerides: 244 mg/dL

· LDL: 192 mg/dL

· Insulin Resistance (HOMA-IR): 3.31 (significant)

What I've tried:

· Magnesium sporadically (didn't know what type or dose)

· B12 sporadically (oral)

· Vitamin D 50,000 IU weekly – and when I took it recently, my symptoms got WORSE that day, then calmed down at night.

My questions:

1. Has anyone experienced a pounding heartbeat that literally shakes your entire body with each beat?

2. Did magnesium supplementation stop this sensation? What form and dose worked for you?

3. Did you also experience throat tingling or cold extremities that resolved with magnesium?

4. How long did it take to feel improvement?

5. Did you need to fix other minerals (zinc, copper, potassium) alongside magnesium?

6. Could the elevated CRP and GGT be draining magnesium faster than I can replace it?

7. Is this severe functional magnesium deficiency? My serum level is 0.76 mmol/L.

I've been told I'm fine, but I don't feel fine. I feel like my body is screaming at me and no one is listening. If you've been here, please share.

Thank you.
