What Causes Pressure In Lower Abdomen, Bloating, Flatulence And Belching?

Question: Dear Doctor,

3 days ago I started feeling pressure and a sharp feeling in my lower abdomen, bloating, a moderately increased need for belching and emitting wind. At first it felt like a need to empty my bowels but only air came out of me. The pain is quite bad - it keeps waking me up from sleep.

It hasn't improved at all. In addition to those symptoms, I've lost my appetite and I almost didn't eat anything yesterday. As a result, I haven't needed to use the toilet for two days now.

I also caught a cold two days ago but I don't have a temperature. I'm not feeling very well in general.

Before Christmas, I had occasional problems with stomach for the last few months, some of them similar to the ones above but much milder.

I have a history of stomach ulcers (15 years ago).

Do you think I should see the doctor and what do you think could be causing this?
I'm not aware of eating anything different from what I usually do. I eat a balanced diet.

Dear doctor Kini,

thank you for your answer. I have a follow-up question. Since yesterday, I've also had a very severe cold or flu or something like that. I've never had anything this strong, my nostrils are completely blocked, one of my eyes is so swollen I can barely open it and I feel it's progressing down the respiratory tract (cough and sneezing). Noise and light are very unpleasant. I also have a strong headache. I don't have a temperature though and I don't vomit.

Do you think this warrants a doctor visit or shall I wait for what happens in the next few days, given the persisting abdomen problems?

I have ibuprofen and pseudoephedrine at home, together with the Avamys (fluticasone), will any of that help?

Thank you.
