One of them is true, you cant give blood for a full 12 months after getting inked. Not sure about the epidural though, shouldn't think it would matter.
Yes, you have to wait 12 months after getting tattooed to give blood.
Epidural Space
No I doubt any tattoo artist would tattoo someone on blood thinners. I have five tattoos and was on blood thinner during each one. I didn't have any excessive bleeding. That is my experience. The tattoo artist also knew. I asked her opinion before hand.
blood accumulation that separates the dura from the inner side of the skull is known as an epidural hematoma (blood swelling). The same process occurrence between the dura and arachnoid layers is a subdural hematoma
There is no evidence that lower back tattoos cause harm in this situation. Initiating an epidural through the ink of a lower back tattoo will not cause ink to enter the blood stream or the spinal canal, or cause further complications for the mother or baby.Source: http://www.lifelinetomodernmedicine.com/ArticlePage.aspx?ID=302a85f8-7135-4174-bd4c-2bc4ad7e04c2&LandingID=fc6eb1da-98e4-43c7-bb9f-09c17e2a005d
during dialysis the blood is is flowin through a closed system
No, The risks of bleeding into the epidural space and causing decrease blood supply to your spinal cord by mechanical compression is to great.
Smoking marijuana before getting a tattoo should have no effect to the tattoo process. Other pain killers like Advil before a tattoo on the other hand will thin your blood and cause bleeding during the process.
No
Epidural hematoma
I presume you mean an epidural blood patch. If so: An epidural blood patch is a surgical procedure which uses a person's own (replanted) blood to close any holes in the dura mater (tough outer layer) of the spinal cord. It can be used to relieve headaches caused by a spinal tap.
yes a tattoo in not in your blood stream it's in your skin you can donate blood
