Have redness up both sides of my neck,in front, on the out side. but still regular skin tone down the middle where adams apple and down pipe is.the redness does not itch at all, but i feel tightning in my lower throut where my thyroid would be?

Even you do not itch you may have allergic reaction and angioedema could not be ruled out. If you are taking a new blood pressure medication please let us know the name. If you are not taking medication before that happened, please recall what you had eaten before the symptoms occurred.

It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor. Wish you good health!
