Injecting near the psoriasis any benefits ?

[Caroline]

The reason for that location is that the now visible DNA that is in the blood has to be taken to the production center of the T-helper cells. That is to be done by the lymphe system.
There is a concentration of lymphe access buttons under your arms and in your groin.
Injecting under your arm is bit more risk full as there are large veins also under your arm

Interesting, I understand the lymph access buttons as you say but now you have me thinking.

#1 Is it best to inject a Bio near the psoriasis.

#2 Is it best to inject it near a Lymph.

#3 Or it makes no difference where you inject a Bio as long as it is within the recommended sites

I am guessing it would be #3.
For me, see my earlier post, #1 would make no specific sense, as I think the location is not relevant.
#2 also makes no sense to me. You are not trying to learn the immune system something, like I am doing with the autovaccin therapy, you are targeting cells in your body to be less sensitive or better blocking at all one of its receptors.
It might even be #4 A place where the bio can stay and will gradually be absorbed by your body, and probably those are the recommended sites. I think the belly, with its fat layer would be excellent.
