In such cases it is very important to note any other conditions like stress, confusion, memory loss,
alcohol, drug, and medication history (
hydrocodone) is also important.
As it is evident that hydrocodone might have led to hallucinations. I suggest you to take prescribed dosages otherwise can take non-opioid analgesics like ibuprofen, diclofenac etc. I suggest you to consult physician. Take care and regards.
