If you don't like needles, I have some advice about not screwing up your joints. Take good care of them. I have bad shoulders (left shoulder the worst of all) and knees. I have to go in to the orthopedic doc. 4 times a year to have fluid removed from my left shoulder, and then cortizone and lidocane? injected in. There's nothing needle wise as intimidating as seeing that 18 ga. needle (looks like a Mcdonalds straw with tip angle cut) and friggen test tube sized syringe going into the top of your shoulder joint. Then after that pain, you actually don't mind the 20 ga. needle cortizone shot with an equally large syringe that seem to take for ever to empty as he moves the fuken thing in a bit of a circle..
Needles.. Man, until you get shots like that, or donate plasma, those are needles.. Or I guess the proper term is "cannons"..
Good luck on your blood work and headaches.. I still get them from D.ball, but I have noticed a drop in itensity after more food and water intake..
