Meh, like yeah if it’s happening a lot and you have a inflammation/rash/broken skin then yeah get that checked.
Don’t know a doctor who will give the time of day if i show up saying, “my hand was itchy for two minutes a couple weeks ago and this happens a handful of times a year and it feels good if i use my teeth to dig in”…
Volunteer in outreach orgs or at events that are related to your interests.
There are also mutual aid orgs. They are almost always accessibility aware. Maybe check in with MADR. They may be able to point to local groups if you’re in the US.
There’s also Food Not Bombs which is great!
