I blieve when I did some research last year I found that Bloodwood and Purple Heart can be very toxic. It sounds like you are having a very severe allergic reaction, be careful because the next stage in swelling may very well lead to swelling of the airways and that can mean a new avatar for you. Very bad, don't waste time with an Internist go straight to an allergist. The allergist can perform a skin or Rast test and determine the source, it may save you a trip to the ER.
We have a lot of allergies in our family and we have found that people's sensitivities to allergic sources can change quite a bit as they grow older. So do not assume that since you did not have a sesitivity to some woods or chemical compounds when you were younger that you do not have them now. Good luck.
