Ulcers typically cause pain in the abdomen between your breastbone and navel. They can also cause  nausea, weakness, loss of weight, etc. but I can't find any reference to joint pain. I am not a doctor and only a doctor can diagnose you but I recommend that you tell your physician about these pains - they may not be connected to your ulcer.

I wonder if any of them could be a reaction to the medication that you're taking? (Did you experience them before you went on the medication?). I was unable to check on those drugs - I think the spelling is incorrect. You can easily type in the name of the drug and look for side effects if you think that's a possibility. Good luck.
