Hi, For The Last Three Days I Have Had Severe

Hi, for the last three days i have had severe pain in my left lower abdomen. i feel that its bowel related. i often have severe wind.
for the last two days i now have severe pain in my lower back left side. i havent been able to get comfortable in bed, tossing and sore whatever position im in. heat has helped the area. so far. paracetamol not much help.
