Above discussed pain usually doesn’t respond to regular analgesics (painkiller) medicine and require nerve medicine in right dosage. Pain, which is resistant to medications, can be effectively and safely treated by minor procedures which include Nerve blocks, Botox injection. Another treatment method is RFA (radiofrequency ablation) technology which ablate the specific pain fibres and hence effective for long term.
These procedures are usually safe and can be done on day care basis.
