Hi, Im looking for advice. About a week and a half ago I started to have lower abdominal pain and lower back pain on the left side of my body. I started to think it may be a kidney infection so I started to take Cranberry tablets. I vomited once and felt unwell. After a couple of days the pain went and I stopped taking the cranberry supplements. I went out on Friday night, was extremely nauseous the following day and the pains came back.. even worse than before. Now the pain has also moved to the right side! What could it be? Im scared!
