Suggest Treatment For High Blood Pressure

im a 41 yr old african american woman 5 6 high blood pressure. I have a few questions. 1. Why after eating jalapenos does my right nipple burn/hurt. 2. I had a partial hystorectomy 2ys ago ever since then It seems like I stay dehydrated to the point where i just cant seemto get enough water and when I got to urinate its not yellow it looks like redish brown. I went to the doctors becasue my lower left back was hurting and my face seems to keep getting darker and darker they ran test showing that my kidney function was good no stds the only thing she said is that I could be dehydrated. Can severe cause this? 3. about 5 yrs ago during the summertime I was sitting in the sun at a cheerleading compeition from 8am-6 it was very hot and i had some pants that came just past the knee although sitting under a tent my legs were exposed to the sun. I felt them burning so I would try and get them out of the sun,,,,now yrs later especially on FRONT of my right leg right, right above the calf and my ankle my skin seems to be thining out and my bones seem to be detieriating and seem to be a dark spot where the bone is. What could be causing this. Thank you for your response
