Solar plexus symptoms and conditions

I've been using Lisinopril for about a year and have experienced almost all of the side effects that everyone else has described. I have frequent severe sweating, headaches, sinus pressure, sore throat, tickling throat, annoying cough, frequent periods of when my face and solar plexus area feel very hot and/or flushed though my face looks normal, dizziness, weakness, fatigue, depression, no energy or motivation......etc, etc, and I did not have any of these problems before. Not sure what else to take. I've read side effects for all bp medications and none of them seem like anything I want to experience. Is there anything that people have found to work that has very little or no side effects? This stuff works but I'm so tired of feeling run down. I tried natural remedies, diet change, exercise, etc, before going on the Lisinopril but those did nothing to lower my pressure.

I was prescribed Levaquin for a sinus infection. I finished my last pill (10 days worth) Sunday (3 days ago). On Friday (5 days ago), I woke up with discomfort - dull pain in my stomach (solar plexus area) which has continued. On Sunday, I took Maalox and got diarreah. Since Sunday, I have experienced alot of gurgline, as well as, dull pain in stomach, upper and lower intestines. It seems to improve temporarily when I eat something. This morning (Wednesday) I had painful gas. I just called my gastro doctor and he can't see me for 2 weeks. Help!
