Can taking to many laxatives cause serious stomach issues, like ulcer? i've been taking lax.per dr. cause constipated but been having tummy pains

Absolutely-depending: on agents, quantities & what altered responses which happen within you. Many laxatives stimulate ↑ed intestinal activity, contractions, intestinal cramping. While ulcers unlikely, intestinal cramping can be quite variable & painful. Agents may not be effective & may promote future constipation. Your primary physician always=self. (Docs advise, paid for treating client's problems, not successes.)
