Whats with Astros doctors

Paredes – Supposed to be a simple hamstring injury predicted 2-3 weeks out, now it is
"more serious" then they thought and has to get a second opinion.

Alvarez – 10 day IL for soreness in hand, coming up on being out for 3 months.

Tucker(last year) – 10 day IL for shin injury out for over 3 months.

Is it the doctors are bad or is the GM straight up gaslighting us.
