Hi, just check whether
1)There is any associated neck pain
2)Any radiating pain towards the upper limbs
IF so it is related to cervical spine problem. Then u need to take medications, soft cervical collar and physio.
IF not then give pain killers, and hot fomentation and wait for three days if the pain is subsiding, No worries.
Next Steps
U can get me back after checking the above.
Take care
