Try capitalizing the first letter of every line.
spitting
Was this supposed to be "spilling"?
a bullet stuck between
A medic memorizing data
of how to heal a wounded man
A bullet stuck between what? The medic?
data of how
on, not of, I think.
maybe
May be. Space!
and cautiously fearing
that the same situation
could further happen to him
Cautiously fearing is a bit redundant. Actually, "cautiously" in that sentence seems entirely unneeded.
Who is "him"? Is it the medic?
could further
Could also. Further doesnât work very well, I think.
and he is cornered in combat
with the reinforcements reaching
and the man threats to kill him
Ok, so who is cornered in combat?
What reinforcements? Whose reinforcements?
What man? And I think itâs âthreatensâ. Threats is a noun, not a verb.
It seems like this man sort of popped out of nowhere while the narrator was being attended to by the medic.
with a bullet to the chest
Who got shot?

Ok. First of all, I hope you don't get offended by all of this, but a critique is in order.
I think the biggest issue in this poem is who you're talking about. First it looks like you're talking about someone who's gotten shot, then you've got the medic being attacked.
Then, technical stuff.
Be sure to read over your poems before submitting them.
You could use a bit more punctuation. Commas, periods, all that.
And spelling. Make sure you use the right word. Using the wrong one can be a bit confusing. Those red squiggly lines are there to help you!
Like I said before, try capitalizing the first letter in each line. It works wonders, I swear.

I really liked that last poem, though. Just a bit more was needed.
Maybe you should edit it and write a new version. It'd help.
