For the past 2 years or so I have been suffering from mild on-and-off stomach discomfort, not really nausea but it's "upset". During this time I have been very inactive, partly because of my stomach.
It was never a really terrible problem so I didn't see the doctor about it until recently. He did blood tests and an ultrasound, and it all came back fine. I find myself unable to swallow pills so I was prescribed liquid Zantac to help with the acidity in my stomach. I've been taking it for about a week and the discomfort has gotten quite a bit worse.
It's even more sporadic now, coming and going for minutes at a time. When it's not as noticable I think I feel better than before I was taking Zantac, but when it strikes it's quite a bit worse. It seems to come and go at random, not really affected by eating. Along with the discomfort I usually have mild gas and occasionally (but rarely) get a foul taste in my mouth.
I also have another problem that may or not be related to my stomach problems: Constipation. I don't really have a problem that I "can't go", but when I do there is excessive straining involved and I sometimes have a different kind of stomach/abdominal discomfort after going. I believe I have also developed occasional hemorroids as I have felt a lump that has since gone away. I also believe I may have a recurring anal fissure from the straining, as I sometimes feel pain/burning when passing stool and have had blood on toilet paper.
My diet for quite a while has not been good, along with me being inactive, so this could be causing my constipation...although the past few days I have been exercising regularily and trying to eat healthier. I have seen no change other than my stomach has been worse.
So needless to say I am very worried about this. It could be the medication giving me this extra discomfort, as side effects can be upset stomach and constipation, which I already have anyways.
I realize all these things described together create a very complicated problem to diagnose, but I'm desperate for some answers. I am waiting to see what effect the medication has further before returning to the doctor.
The stomach issues can be something of a concern, but as with all things you're better off seeing a doctor if you have persistant symptoms. It could be anything from gall stones through to a tummy ulcer which causes those kinds of things, or even a simple diet issue or bacterial infection. A diet rich in fibre is always good for keeping you regular and it's never too late to change your eating habits. Sadly, most of the processed foods we have in western society is poor for us and it's criminal that more light isn't shone on the companies that put profit before public health (but that's another arguement).
I'd go back and see your GP and arrange to get a referral to a gastro specialist to get further tests done. A blood test and ultrasound from the GP is usually the first of the 'non evasive' proceedures they'll do to see if there's any obvious problems, the next step will be seeing someone who can take the tests to the next level. A Endoscopy and Gastroscopy will allow them to get a good look to see if you have anything going on in there (try not to worry, minor things can just as easily cause the symptoms you're getting at the moment, but it always pays to be thorough) or perhaps they might recommend an abdo CT scan as well.
In the meantime, I'd recommend cutting back on the fats and sugars and get more fibre in your diet. For an acidic tummy, I personally use Mylanta which works for me, although depending on which country you're in it might go by a different name.
The best thing you can do though is go back to the GP and ensure they are aware you're still having symptoms so they can refer you to the next step. It's through process of elimination and investigation they'll get down to what's giving you grief.
Try not to worry mate and be persistant with your GP. If he can't find out what's going on, be sure to get a referral to a specialist and be persistant with it and stay positive.
