What Causes Pressure On Neck?

I have been feeling pressure on both sides of my neck & become short of breath. Especially when squatting down and working on things such as cleaning out cabinets. I also have some swelling issues in my ankles & hands. Yes, I take medicine fore blood pressure & honestly, that was my first though, my blood pressure may be up. I also have some imflamation in hands & feet, I recently had a cortisone injection & also take voltaren for carpal tunnel. Why do I feel even more swelled when taking an anti-inflammatory medicine? Thanks. I am 36 year, female.
