I am in the process of proving my immune deficiency, I retest on the 17th. I have done the IGG injections for 6 months. Heres my question, I had no idea IVIG would directly help with the Lyme, you say it is better than doxy?? If you do the IVIG, will you need antibiotics also? Thanks. Also I wanted to say, you do not need a line, I know many people than do it weekly and it is through a vein in the arm like any other IV. D
