HI, thanks for using healthcare magic
The stinging sensation may be
neuralgia which is nerve related pain.
Nerve related pain/neuralgia may be stinging in nature. It can also be described as
tingling, burning, sticking, sharp etc
It is due to abnormal function of the nerves and can be temporary or permanent.
Causes include : (1)trauma to the nerves supplying the area. This can occur in the back or along the path of the nerve
(2)diabetes
(3)abnormal levels of vitamin b6
(4)low levels of
vitamin b12 or folate
(5)liver or
kidney disease
(6)side effect of medication
(7)exposure to toxins
(8)abnormal levels of
thyroid hormone
You can consider monitoring it, if the symptoms are not severe. If they are severe or worsening then you should see your doctor for assessment.
This would involve a complete history, examination and some investigations
Treatment would depend on the cause found
I hope this helps
