Post-procedure, you can expect the area to feel swollen and mildly painful, often compared to a dull ache. This is a good sign indicating the injection is working.
The injected area will also become mildly inflamed. This is because when your body sustains an injury, the area becomes swollen to start to the natural process your body uses to heal itself.
Steroid injections and anti-inflammatories such as ibuprofen do the opposite. These methods are good for relieving pain but will slow the healing process.
After 2-5 days you can expect the pain to start receding.
The injection will increase strength in the area, reduce pain, and improve overall function for the long term.
