Renal Hypertension

I have had renal hypertension for quite some time, 15 years or so. The high blood pressure has never been really controlled and the med that medical Dr. gave me only made me feel bad. In late November of 06, I had a problem with my eyes and the Dr. said my BP was 250/120, I got a prescription which didn't lower my BP much and made me itch and have leg cramps. I was then diagnosed with an inner or middle ear infection and kidney failure. I also have a large tumor in my right breast that has a 90% chance of being benign. I am now taking a herbal tincture (rauwolfia and linden)that lowers my BP to an acceptable level with no bad side effects but would like to find a homeopathic remedy to cure my kidney problem and stop the tumor from growing. I am 68 years old, 50 pounds overweight, raising a 7 year old hyperactive grandchild (adopted), have been under extreme stress for the most part of the last 18 years. I am somewhat depressed right now, sleeping ok except waking up to go to the bathroom several times a night. I am tired much of the time and not doing the work that I used to do (outside, Inside, etc) My nose and ears are congested, my head aches off and on mostly in the forehead area, my joints ache and I have muscle pain over most of my body. I am usually easy going and happy but I find that I am more tense and shorter tempered than normal and I don't like that. Help
