Leg cramps and paralysis symptoms accompanied by pelvic and hip pain [Question]

Went hiking with my close older sister on the weekend, and it was heavy.

I heard that men are doing long dumbbell exercises.

The next day, I woke up and felt it from my right lower back.

Pain extends to the pelvis and hip joint, and it feels throbbing.

I visited the nearby neurosurgery.

He told me to lie down and lift my leg.

I got an injection because my muscles are tense and knotted.

Physical therapy hot pack, gel massage, hand massage, electrical therapy

They also provide medication maps and prescribe gels at the pharmacy.

I often experience pelvic and hip joint pain.

I saw somewhere that it's called aging.

Are there people like me?

On days I walk a lot, it starts from the big toe.

I have a cramp all the way down my leg, and it's painful.

Should I visit other hospitals as well??
