I have had diarrhea for around 4 weeks and constantly need to strain there has been some blood but not evertime . I have been bloated and have intermittent stomach cramping I have not changed my eating patterns and is not worsened by what I eat. I am struggling with my energy levels and am finding it hard to get up in the morning even after plenty of sleep. This week I have noticed horizontal ridges appear on my small toe nails, should I be taking vitamin supplements? I have a shortness of breath and have spent the last day in bed but am still tired and have been suffering with the sweats. Should I be concerned? Any help would be great
