Go to an urgent treatment centre or A&E if:
- you have severe pain in your arm and it's difficult to move
- you've injured your arm and you heard a snapping noise or your arm has changed shape
- your arm tingles or feels numb
- arm pain has come on suddenly and it occurs with pressure, heaviness or squeezing across your chest
This could be a sign of a heart attack.
Apart from an injury, these things can cause arm and elbow pain.
Do not self-diagnose. See a GP if you're worried.
If you have elbow or arm pain, you might be able to refer yourself directly to services for help with your condition without seeing a GP.
