A few sentences

[nyggus]

Hi, are the following sentences correct?

"This is just too painful... I've heard that your hand is as big as a bear's hand, but I haven't imagined it is so big! (Well, in fact, it's as huge as the Bigfoot legend is.) Then, it is really too hard for me to hold your hand: I feel like I would hold a baseballist's hand (the one wearing a glove)."

Thanks,
Nyggus

Assuming this is direct speach to someone: the verbs in the first sentence need changing (I had heard that your hand was...); the first parenthetical simile is comparing the hand to the size of the legend of Bigfoot (and not Bigfoot's hand), I am guessing you didn't mean this; the mood of the verbs in the final clause (I would feel like I was holding); I'm not sure "baseballist" is usual (I'm not American), if not, baseball player would be better. So I would suggest as follows:
"This is just too painful ... I'd heard that your hand was as big as a bear's but I hadn't imagined it was so big! (Well, in fact, it's as huge as the legendary Bigfoot's!) So, it is really too hard for me to hold your hand - I'd feel like I was holding a baseball player's hand (the one wearing the glove)."

I would use 'hadn't imagined' and 'was holding/would be holding'.
