These are my own thoughts
Random… in truth
From pondering science
And seeking for proof
When the Savior in agony
Sweat blood from each pore
Did this happen literally
Or was it a metaphor?
I read of a woman
Who said this does occur
She spoke how it happens
Her body in emotion
Leaks through inflammed cells
And amidst this commotion
The strength in her pales
Restates this rare occurrence
With the most painful education
Christ was pressed for endurance
15 Therefore I command you to repent—repent, lest I smite you by the rod of my mouth, and by my wrath, and by my anger, and your sufferings be sore—how sore you know not, how exquisite you know not, yea, how hard to bear you know not.
16 For behold, I, God, have suffered these things for all, that they might not suffer if they would repent;
17 But if they would not repent they must suffer even as I;
18 Which suffering caused myself, even God, the greatest of all, to tremble because of pain, and to bleed at every pore, and to suffer both body and spirit—and would that I might not drink the bitter cup, and shrink—
19 Nevertheless, glory be to the Father, and I partook and finished my preparations unto the children of men.
20 Wherefore, I command you again to repent, lest I humble you with my almighty power; and that you confess your sins, lest you suffer these punishments of which I have spoken, of which in the smallest, yea, even in the least degree you have tasted at the time I withdrew my Spirit. (D&C 19:15–20.)

Luke is also the only gospel writer to mention the bloody sweat, possibly because of his interest as a physician in this rare physiological phenomenon, which spoke elequently of the intense spiritual agony Jesus was suffering… (Dr. Henry M. Morris, The Defenders Bible, arginal notes for Luke 22:44)
Although this medical condition is relatively rare, according to Dr. Frederick Zugibe (Chief Medical Examiner of Rockland County, New York) it is well-known, and there have been many cases of it. The clinical term is “hematohidrosis.” “Around the sweat glands, there are multiple blood vessels in a net-like form.” Under the pressure of great stress the vessels constrict. Then as the anxiety passes “the blood vessels dilate to the point of rupture. The blood goes into the sweat glands.” As the sweat glands are producing a lot of sweat, it pushes the blood to the surface – coming out as droplets of blood mixed with sweat.
