Hi Herny, (

) Welcome.
Yes, it's a medical term—it does not mean you're an addict or that the doctor thinks ill/less of you. Technically, it means that your body has acclimated to the presence of opioid pain medications, so that to discontinue would bring about withdrawal symptoms.
IMO it's important that people—pain patients and their support networks (family, friends, etc) in particular—know & understand definitions related to these matters in order to avoid/end stigmatization of people who legitimately need/take these medications responsibly.
