Hi, ive been suffering with this problem for 4-5 weeks now, it has worsened within the past 3 weeks.. when i wake up in the morning i have a belly filled with gas which takes me ages to expel and it very painful, i have a burning sensation in my stomach and often back, i also have nausea and dizziness often during the day, my doctor said it was ibs but this seems very random and im wondering if it could be a bacterial infection
