Hi..
Thanks for the query..

As per your complain a painful lump which is reddish blue in colour suggests that there is perforation of the blood vessel while insertion of the needle leading to spillage of blood into the adjacent soft tissues leading to formation of a HEMATOMA..

Pain can occur in case if the nerve fibres are also pricked during needle insertion leading injury of nerve fibres and eventually causing pain..

The swelling and discolouration will slowly resolve as the hematoma will slowly get disintegrated and the nerve healing will take place..

You can apply alternate hot and cold packs over the lump for faster disintegration of hematoma and relief..

In case of pain over the counter painkiller like Ibuprofen can help..

Hope this helps..

Thanks and regards..
