After eating, stomach pain/burning travels down abdomen esp. Left and right sides. Abd. Hurts when pressed on. Dr.says too much acid in body. Thoughts?

Maybe. There are many causes of belly pain, some of which are simply annoying, others are deadly. Assuming your doctor did thorough interview & exam, if stomach acid seems to be most likely cause, then high dose omeprazole (Prilosec) can help determine if acid is to blame. If symptoms persist, then other causes should be investigated. Acidity usually affects only upper, central abdomen.
