Hi, I would like to ask you, please, what can cause a suden higher blood preasure? Could it be flu? Infection? I have had usually low bp, but lately (last year) it happens I sometimes have 130/90 or similar bp. I should also notice that I have had problems with sickness and stomac pain last few years. In January (1.12.) I finally had appendix (was bad), Meckeli divertickeli and cysts/endometriosis surgery. After the surgery I had infection. The healing process takes a long time... Thank you very much for your answer. Katerina
