Increased BP, Taking Allergy Shots. Placed On Metoprolol, Thyroid Normal. Breathing Trouble If Shots Stopped. Suggestions ?

My Doctors and I are trying to figure out my mystery. I just began allergy shots 3 months ago. My blood pressure and pulse have always been normal. Since 7/21/2013, my blood pressure and pulse have gone up drastically. I was sent to have a d-dimer work up. The test came back at .7. My doctor requested I go to the ER because he thought I might have a PE. The d-dimer at the hospital came back at .97 - yep, higher, however, my lung scan came back normal. I have been placed on 12.5 mg Metorprolol. The blood pressure is staying down but the pulse still ranges between 90 and 110. Then, thoughts of Thyroid issues came up, so I had a thyroid scan. Yep, Normal. I decided not to have my allergy shot this week to see if the shots have anything to do with the sudden increase in blood pressure. Not really feeling much difference in skipping the shots vs. getting the shots. Oh, and my nasal passage seems blocked. I have been having a hard time breathing through my nose. cant even do a nasal rinse. It wont come out the other side. Any suggestions? Feeling pretty miserable here and I don't have time to be miserable or down for the count......... Thank you - AAAA
