Thorn in my side I know what thorns are in my side. Like the Psalmist said, "My sin is always before me."
Crown of thorns Jesus himself, being God Incarnate, Immanuel, God with us, fully God and fully man. Because of this, He had no sin nature therefore he could not be tempted by his own evil desire. He was led out to the desert fast and pray and to be tempted by the devil, the Tempter himself. Fast- forward another 3 1/2 years or so and another event in the earthly part of his life was something that helped him to experience more fully what it felt like to be human. Before the spear was thrust into his side, he was beaten, scourged, spat upon, kicked, called vile names and insulted. Then, though he had no "thorn" he was given a Crown of Thorns. I'd love to believe it was placed gently upon his head yet it's pretty obvious that there was no care given by the person who did it. Perhaps caught up in the moment, egged on by his peers and the crowd, he more than likely mashed it down, forcing those thorns deep into his flesh.

The Agony and the Ecstasy
Numbers 33:55-56 “ ‘But if you do not drive out the inhabitants of the land, those you allow to remain will become barbs in your eyes and thorns in your sides. They will give you trouble in the land where you will live. And then I will do to you what I plan to do to them.’ ”
