Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems like when the injection was given the pricking needle has caused traumatic
injury to the soft tissues as well as terminal nerve fibres leading to inflammation and pain..
The red inflamed lump seems to be due to inflamed soft tissues as well as the injection needle might have caused rupture to small blood vessels leading to
Hematoma formation and the hematoma gets encapsulated with ruptured fibres, inflammatory cells and broken blood vessels..
Nothing to panic, you can take anti-inflammatory painkiller like
Ibuprofen, apply a numbing gel containing Lignocaine, do alternate warm and cool compresses and apply
Heparin containing gel for faster disruption of clot and regression of the lump..
You can also apply a
steroid gel to reduce inflammation and eventually pain will reduce..
Hope this information helps..
Thanks and regards.
