I have had chemo and radiation and was given a couple of b12 shots. I talked with the pharmacy and they said to take b-12 1000 mcg that desolve, Magnesium high potency 400mg. Also cranberry capsules 3 times a day for pressure.I've had 2 cultures and both have been neg.I am also on Folic Acid from my doctor @ 1 tablet per day -1 mg. Now I'm breaking out and I wasn't doing this before except when taking radiation? Can you help?
