Im not sure, but I think it takes a fast longer to cure a disease than a week. Symtoms might subside in a week, but I would think it would take the whole thirty days, to cure something so serious.
You could change your diet, get a Colloidal Silver generator and a medical grade ozone generator and postpone your spinal tap for a month. If in a month your not doing better go with the spinal tap. If you do CS, ozone, good diet there is no way you'll feel bad enough to want a spinal tap. You will have more money in your pocket as well.
