Hello your symptoms are not normal post-workout soreness — especially the collapse, dark/blurry vision, chest tightness, ear blockage, severe dizziness, and sleeping for two days. That deserves medical attention.
Because this happened twice after adding squats (a large leg muscle exercise), several possibilities stand out:
1️⃣ Vasovagal syncope (exercise-induced fainting)
When you suddenly stress large leg muscles (like with squats), blood can pool in the legs. If:
You held your breath (Valsalva maneuver)
Stood still after finishing
Were dehydrated
Or stood up quickly after resting
You can get:
Nausea
Tunnel/dark vision
Ear pressure
Dizziness
Collapse
This fits part of your story — especially the dark vision and collapsing on the tiles.
2️⃣ Blood pressure or circulation issue (Orthostatic intolerance)
You mentioned: tight chest when standing dizziness when waking and standing
That suggests your blood pressure may be dropping when you stand (orthostatic hypotension).
3️⃣ Electrolyte imbalance / dehydration
Squats use much more muscle mass than push-ups and pull-ups. If you:
Didn’t hydrate well
Were low on sodium/potassium/magnesium
Didn’t eat properly
You can get: Leg cramps
Diarrhea
Dizziness
Fatigue
Feeling feverish
The cramping on the grass strongly suggests electrolyte involvement.
4️⃣ Overexertion / nervous system overload
Large compound leg exercises can spike:
Heart rate
Blood pressure
Adrenaline
If your body isn’t adapted to them, it can cause a crash afterward — especially if you pushed hard on a new movement.
5️⃣ Something more serious (must rule out)
Because you had:
Collapse
Chest tightness
Severe dizziness
Visual changes
You should rule out:
Heart rhythm issues
Blood pressure disorder
Anemia
Blood sugar problems
Post-viral weakness
POTS (postural orthostatic tachycardia syndrome)
These require proper evaluation.
What to do for now
Until you see a doctor:
✅ 1. Hydrate properly
Before workouts:
500–700 ml water with electrolytes (not just plain water)
Eat carbs + salt beforehand
✅ 2. Do NOT hold your breath during squats
Exhale while pushing up.
✅ 3. Reduce intensity drastically
Start with:
10–15 slow air squats
Rest 2–3 minutes
No pushing to failure
✅ 4. Cool down properly
After workout:
Walk slowly for 5–10 minutes
Don’t stop abruptly
Don’t shower immediately while overheated
✅ 5. Don’t go outside immediately after a hot shower
Thank you
Hello, thank you for sharing your concern. Your symptoms suggest that your body is not tolerating the sudden addition of intense lower-body exercise. This might be due to Sudden blood pressure drop / Dehydration and electrolyte imbalance / Post-exercise vasovagal response, etc. Here is my advise-
1. Before workouts- Hydrate well (500–700 ml water 1–2 hrs before). Eat a light meal/snack containing carbs + salt. Start squats gradually (very low repetitions initially)
2. During workouts- Avoid breath-holding. Take rest intervals. Stop immediately if vision darkens or severe dizziness occurs.
3. After workouts- Perform 5–10 minutes cool-down walking. Rehydrate with fluids containing electrolytes.
4. Consult a doctor if: You collapse during exercise. Chest tightness or occurs without exertion. Heart racing or irregular heartbeat occurs. Symptoms appear even with mild exercise. Persistent fatigue, anemia symptoms, or frequent leg cramps.
5. Also consider getting these tests done - BP check, CBC, ECG, Sr. Electrolytes. Review with reports.

Hello
Most likely cause:
A combination of sudden lower-body exertion (new squats), dehydration/electrolyte imbalance, and post-exercise blood pressure drop.
This can cause dizziness, nausea, blurred vision, cramps, and near-fainting.
Showering and going out immediately after intense exercise can worsen it.
What to do:
Start squats gradually (low reps, slow progression)
Hydrate well and include electrolytes (salt/potassium)
Eat a light carb snack before workouts
Cool down and avoid hot showers right after training
Stop exercise if symptoms start and lie down with legs elevated
Seek medical check if episodes continue: blood pressure (including standing), ECG, blood count, electrolytes.
Persistent chest tightness or fainting → urgent evaluation.
I trust this helps Thank you Take care
Hello dear See as per clinical history it seems overexertion Usually adding a strong exercise will result in excess burning of calories which will cause hypoglycemia. I think that could be reason. I suggest you to please Gradually start new exercise with slow frequency Take balanced diet and zincovit multivitamin Avoid skipping meals Avoid refined food Hopefully improvement will occur Regards
Your symptoms suggest that your body is likely not tolerating the sudden addition of intense lower-body exercise (squats) well, rather than a simple muscle issue. Squats recruit very large muscle groups, which sharply increase oxygen demand, blood flow shifts, and fluid/electrolyte loss. If your conditioning, hydration, or blood pressure response is not adapted, this can cause exercise-induced dizziness, nausea, fainting/near-fainting, leg cramps, and temporary vision darkening, which are signs of reduced blood flow to the brain (similar to vasovagal or exertional hypotension). However, because you also described chest tightness, collapse, severe fatigue lasting 1–2 days, and ear blockage, this should not be ignored, as it could also relate to anemia, dehydration with electrolyte imbalance, low blood pressure, or occasionally a heart or circulation issue.
The safest approach is to stop intense workouts for now, restart gradually, hydrate well with water plus electrolytes, eat a proper meal with carbs and salt before exercise, warm up slowly, and avoid sudden heavy squats. Most importantly, you should see a doctor for a check-up to rule out medical causes with basic tests like blood pressure, hemoglobin (to check for anemia), blood sugar, electrolytes, and possibly an ECG, especially since you experienced chest tightness and near collapse. Until evaluated, avoid pushing yourself hard, because passing out during exercise can be dangerous.
Your symptoms (severe dizziness, nausea, near-collapse, chest tightness, dark vision, leg cramps, extreme exhaustion) after squats suggest possible exercise-induced low blood pressure, dehydration/electrolyte imbalance, overexertion, or a heart or circulation issue, and this is not normal after routine exercise. Stop intense workouts for now and get checked by a doctor for blood pressure, ECG, blood tests (hemoglobin, electrolytes), and fitness evaluation before continuing training. Start again only gradually with proper hydration, warm-up, and supervision once serious causes are ruled out.
