Strange Symptoms

I started premarin about 6 years ago. I take .9 mg per day. I have noticed some strange symptoms within the past year and I am starting to worry about the side effects. I am wondering if anyone else has had these symptoms. I have pain in my left shoulder blade - which I think is muscular - but it is causing numbness in my left hand and both feet. My ears ring in the evening after I eat and I have heart palpations within an hour or so after eating in the evening. I have recently been diagnosed with diverticulitis and ibs.....I am only 38 years old. I have tried to come off of the premarin several times, but the hot flashes are unbearable as I live in south florida. I recently had a bone density test and it determined that I was at risk for osteoporosis with a heel bmd t-score of -1.0. Unfortunately I do not have healthcare and I am reluctant to go to the doctor. My mother died of breast cancer in her 50's and I have had two benign cycts removed from my left breast that were apparently the type of nodules with cells that have been determined to turn into breast cancer......I now feel a lump in my right breast.......When I stop taking the premarin, immediately I start with the hot flashes, can't sleep, just feel plain miserable. I tried black cohosh and soy, but nothing on the market seems to help............Any advice or suggestions would be greatly apreciated and welcomed.
