Is it normal for your tattoo to still be raised two weeks after the first session?

2 weeks ago I had my first laser tattoo removal session on my side of a script tattoo. Some of the lines are almost completely gone but the dark ink within the letters is raised and extremely itchy. Is this a normal part of the healing process? Or am I having an allergic reaction? When can I expect the raised skin to go down? I must note that I didn't blister.
