I h ave also of allergies - went thru testing= main allergy was to dust. But there were slight reactions to most foods. Actually years ago I even got allergy shots. Anyway, I have a new primary doctor- he wants me to use a netipot (I've been using saline spray (similar in effect) but he also wants me to take fish oil, I think 1-2 grams daily. Once years ago I had an allergic reactions to salmon al well as shrimp (vominting) but they are very large portions. Am some what hesitate to try the fish oil- I do take flaxseed tablets, but he really wants me to take fish oil. What do you suggest? Also he wants me to take B12. ( I am 61 years old, a retired nurse, interested in nutrition, but do have BP problems. Any suggestions?
