Brief Answer:Nerve injury
Thanks for posting your query.
The burning pain in the left collar bone area that radiates into left arm and hand is likely to be due to a mild nerve irritation
or injury during the catheter insertion.
This can also be due to following reasons-
-Prolapse of disc in cervical spine
-Cervical stenosis or narrowing of holes from where nerves exit.
-Deficiency of vitamin B12
To help these symptoms avoid bending your neck at abnormal position for long time, like on computer. Do warm water fomentation with help of water bag over your neck.
Take a good analgesic like combination of tramadol with paracetamol
Test for levels of vitamin B12, If low do take Vitamin B12 supplements.
This is likely to heal on its own in few weeks. In case the pain increases or is persistent then do consult your physician for further investigations.
I hope this answers your query.

Wishing you good health.
