Al, just in case you need to hear it again
GET YERSELF TO THE DOCTORS!!!
A mate from my running club had some really severe problems. It started off just having issues during/after running but on occasion its got to the stage where he's had to take time off work cos he couldn't sit at his desk any amount of time without the risk of a toxic waste spillage on the scale of Hungary.
At one stage he ended up really ill in hospital and they still couldn't suss out what was going on.
After much prodding and poking and shoving cameras where the sun don't shine he was diagnosed with er... somethingorotherthatIcantrememberthename!
From what I understand he's got a hyperactive immune system which makes him produce too much stomach acid
Anyway, seems like its mostly well controlled - a combination of meds and cutting certain foods out of his diet. He's back to training and beating us all in races. He still has go through the camera routine every few months as with his condition he's got a much higher risk of contracting something worse.
Not saying any of this to scare you or suggest you've got the same problem - could be one of any number of causes, but the point is he's only managed to get sorted after a long process and being really persistent with doctors to get a proper diagnosis (and not without giving up on running all together a few times). You may need to be prepared to do the same but in the long run a few doctors appointments are well worth the agro and may well save you sick days further down the line.
And just to repeat previous posts, there's absolutely no reason why you should have to use holiday for a doctor's appointment.
It might be worth checking with your HR people what the company policy is before you go to your boss as he'll have to go by that. At worse you'll have to take a 1/2 day unpaid. If its your Sainsbury's boss let me know cos I've got friends in high places who would be more than happy to sort 'im out! :sneaky:
