girlofsteel,
I was looking at some of your past posts. And, it looks like you are a veteran at this game. You've tried atenolol (a BB), verapamil (a CCB), Atacand (an ARB), Avalide (ARB + diuretic) and now lisinopril (an ACEI). It sounds like you dropped them for various side effects. Did any of these have a positive blood pressure response? It's strange seeing someone go from an ARB to an ACEI. Usually, it's the other way around.
Also, in one of your posts you indicated that you have a resting pulse in the 110-139 range. That sounds high. Is it normally that high? Or, was this from the Avalide?
I can relate a little of my experiences. I was on lisinopril + HCTZ for a few days. I had the cough and a nasty throat thing (throat felt constricted; may have been angioedema?) with it. My doctor had switch me to HYZAAR (ARB + diuretic). Wow, did that hit my BP for a couple days. That's why I had suspected a combo effect in your case. In any case, HYZAAR ultimately ended up doing absolutely nothing for my BP.
In my search, there were only two drugs that had any impact on my BP:
One was Cardizem (a CCB). The only problem I had with this one was that it caused a headache (obviously unacceptable). But, otherwise, it had a very good BP response. When I posted about the headache, it seems that others have had this problem. Also, it's available in generic form. So, it can be very cheap depending on insurance. Of course, if you are paying out of pocket, it's rather expensive even as a generic. In any case, this one might be worth trying. If after a few weeks, lisinopril is proving to be side-effect free and gives you some BP control (but not enough), this might be something to try adding to it.
The other is Benicar (an ARB). I am currently on the 20 mg dose (no HCTZ). It is working very well for me. Since, you've already tried two different ARBs and had side-effects, I doubt this one would be any better. Afterall, you did list Atacand (another ARB) as one of your worst.
Oh well, best of luck. And, most importantly, don't put up with side-effects. If they are bothersome, you need to keep searching. I know it is very frustrating.
