Abstract: A method and kit to produce activated autologous platelet rich and platelet poor plasma (AAPRPP) and methods of use to treat pain. The method to produce AAPRPP generally comprising (1) obtaining whole blood from patient; (2) centrifuging whole blood in a collection tube; (3) extracting platelet rich and platelet poor plasma mixture from collection tube; and (4) transferring platelet rich and platelet poor plasma mixture to an activation tube containing at least one platelet aggregator and at least one platelet activator to obtain a resulting platelet concentration. The method to treat pain generally comprising producing AAPRPP and extracting contents of activation tube into a standard syringe then injecting AAPRPP at or near the nerve group responsible for the affected anatomical area.
