Mind, I’ve had many tattoos, but this is the first big one on my forearm and woof my elbow is rejecting this world.
It’s been almost a week since getting it, healing is coming along nicely, but the inner side of my elbow joint is just in crazy pain, especially as my palm faces upwards. Bending is near impossible.
I haven’t done anything with that arm that would otherwise make that kind of pain - like picking up bricks or whatever. So unless I slept wrong for the past three days, my guess is that it’s coming from the tattoo somehow.
Call your tatoo artist and also just to be sure, visit a doctor. Physical (or mental) ailments should be less discussed in the Internet and more in a doctor’s office
