Well, I can only blame Nadal for playing in the exhos, general hercules. Nobody forces him to. If he felt that he needed rest, he could have always canceled them. But the lure of easy money and an adoring crowd is tempting.
Anyway, what I said still stands. As soon as he is feeling well, rested, he should get back and practice on the clay and get ready for Indian Wells. No need for him to play minor hard court tournament like Acapulco. Or if he feels better fast, maybe he'll play on the clay in Rio de Janeiro.
Everything should be healed before he starts back, hand blister, back, stomach, etc. He should be as healthy as possible going into the clay season. History awaits him at Rafael Garros.

So true, masterclass. I read once that Rafa is super hyper. He has to always be doing something. In some respects, he's like a big kid. Still, there's no excuse for not learning how to manage your schedule and peaking for the big tournaments. Every time I think he'll get it, he disappoints
