What Causes Burning Sensation Under The Arm?
Thank you,XXXX
Don't be concerned....
Detailed Answer:
Dear XXXX,
If you don't see a rash and external skin changes, the burning sensation is most likely from a neurological cause. Proceed with the appointment tomorrow. Your doctor will perform a local / systemic examination and run some blood tests / radiological investigations to find the cause. Most often the cause is unknown. In a few cases it may be related to pinched nerve, vitamin deficiency, a viral infection, metabolic disturbance and other common inflammation.
You might be started on vitamin b12 supplements and a drug to reduce these sensation.
Don't be worried. From the history provided, I don't see any sinister concerns.
Hope this helps. Let me know if you need clarifications.
Regards
