My girlfriend is experiencing some atypical symptoms the last few days after a trip we had to Hawaii. Long plane rides made her legs a bit squirmy. She has lower back pain radiating down into her buttocks and upper legs. She went in today to her doc and they tested for a UTI or kidney infection and that is not happening. She has only one kidney after donating one to her father. She called now and said she is having some off/on sweating and heartburn started too noonish today. Any thoughts/suggestions? She is in amazing physical shape with the horse stables and ranch she owns. Stress is a factor as she had two big losses two weeks ago... one of her top student riders committed suicide at onlyt 15... and her great dog had to be put down the same week. Help... Thank you, Ron~
