In the UK we have the 111 NHS non-emergency telephone service - they don’t give medical
advice but triage you based on your symptoms. Either a doctor will call you back, they will tell you to go the non-urgent care centre or A&E (ER) immediately.
In the EU we have 116117 which is not (yet?) implemented in all countries. It's part of the "harmonised service of social value" which uses 116 as a prefix and has also other helpline numbers like hotlines for missing children or emotional support.
call in to 811, get some pre-screening. usually it's "go to the urgent care" or "sleep it off", but it's a good sanity check, and you usually get treated better then you say "811 told me to come in ASAP"
