hmmm... looks like mostly right turns...
plan your trip so that mostly left turns?

best see a doctor

Just how fast are you driving? I agree with dwRK - see a doctor if not sure...

I guess the obvious one is
1. Driver slower when cornering
2. Change better car that handle better at bend + better car seat support
3. Body checkup

Those entry level car usually have very flat seat that doesn't "hug" your body and ass.

inb4 what car? I was less comfortable with the P2 car seat (which I assume they designed for city driving mainly) and an old Toyota (Vios Dugong seat). These 2 cars make me tired more for long-distance drive, which I get it from last company rent car. Drove it from Damansara - Kemaman on Vios.

Err… this one ah, best advice I can give is “proceed with caution and at your own risk”.

probably bad habit sitting position ? Another situation 骨刺？

If nothing is serious correct and adjust your sitting position? , avoid sitting on toilet floor chair ifound quite pain if too frequently use 😂 keep your body straight don't do like cat 腰

Other than that visit doctor first 😆

Posture issue.

If 骨刺 private sector mostly ask you do surgery the time mil do it rm50k+ what i can remember , cost exclude MRI scan etc, janji medical insurance ada RM 150k is more than sufficient

After surgery got to use tongkat,  mostly laying down on bed , no way you can bath your self, need 干洗your hair if no one help you bath and frequently wet warm towel clean up your 鸡鸡 etc and a lot of medicine, and mostly the most you need are pain killer that what i can remember

After 2 month you can drive and walk freely but my mil is very old last time take time compared to you
