So I’ve played outdoor soccer my entire life and I have never had a problem with this before. I always could run through the whole game with little to no problem.

Now that I’m playing indoor my stomach starts hurting painfully bad after a few minutes. No major changes except it’s a smaller field and the game is only 2 23 minute half’s.

The other difference is that outdoor games are usually around 2:00 while indoor games are usually late in the day (8:00-12:00)

We don’t get any warmup time in outdoor (which is usually a problem) however I do try to stretch throughout the game.

Does anyone know what could possible be causing this? Maybe the air quality or something?
