I have nausea and sore to the touch stomach. i am now taking trustan 4mg and have started getting very bad headaches. is this due to the trustan?

Trustan: I would be reluctant to attribute severe headache to trustan. Associated nausea could indicate that headache is part of a viral infection. If your abdomen remains very tender to touch or if severe headache persists, don't hesitate to get evaluated by a physician. In the meantime take in fluids and take Tylenol for headache. Flat,room temperature ginger ale helps settle nausea.
