Could this be allergies?

I am 62. Last August I moved from southern CA to Maryland.

About two months ago I developed a nagging cough...mostly it is a dry tickle in the center of my chest. My nose and lungs are clear. There are times when I feel a discomfort in my chest as well, although it is slight and I haven't felt it for several weeks. It was very annoying. I couldn't talk, especially on the phone, without coughing... and I would cough every time I touched my chest or throat.

I did a master cleans fast for ten days. It didn't help.

I did 7 days on antibiotics...and got very little relief.

I have been taking vinigar, honey and garlic for 3-4 weeks, and it really hasn't helped much either.

I have now been taking Aruvedic herbs for several weeks, and that has helped, but I still have the cough..some days it is almost gone and some days it starts to come back...but I am much better. I can talk without coughing most of the time....

Still, it won't go away and today I coughed more than yesterday...not a good sign.

I went to a doctor and had blood work and a chest x-ray. He says I have a very small spot on one lung...but he does not feel that is making me cough.

He says its allergies.

I have never had an allergy before..to anything. I have no red, water eyes, and very little sneezing...with no runny nose.

Could this be allergies? If not, what do you think it is?
