Does the reason for visit on the Thai visa application and arrival card affect approval, especially for medical care?

How much does your answer on the reason for visit question matter (both on the Thai visa app and the arrival card)? I've just used the general tourist/site seeing answer, but was curious if writing in medical care would help or hinder approvals, or does it not matter? I've been seeing a doctor for an injury sustained here, as well as going to a physical therapist, so part of the reason I'm remaining here is to continue care with the doctors who are familiar with my case. As such, I have a few 60-day tourist entries and exempt entries. I don't know if showing that I'm receiving care here would help with applying for another 60-day tourist visa? Planning to apply for one in Hong Kong.
