Seasonal cold and stomach/gut issue

[fourstardan]

I've had a bad few weeks, ok, it's nothing more than man moans but it aint getting much better.

Went away at half term holiday got a sinus infection/cold, that was sinus initially but got into full streamy nose code, I thought that had gone went to other nostril.

Got rid of it towards the end of the holiday...week after another bout of cold/sinus bunged up, not a streaming cold but now im feeling bunged up and heady. Went to the doc a couple of years ago and he said it was probably fungal.

I can deal with the head cold but I seem to have stomach issues but I've had that gurgling stomach flu feeling last week and struggling after a large meal, yet scoffing like a pig.

Any remedies recommended?
