It’s my 18th birthday next month I am planning on

Patient: It’s my 18th birthday next month. I am planning on getting a tattoo. I plan on getting it on my shoulder/bicep. I am really worried about growth. My doctor says the rate I’m growing I should be at least 6ft. I’m 5’8 now and I have and ectomorph body type. with my arms being long, is it possible when My arms get longer it will stretch my tattoo?

Doctor:
