Here you have symptoms of sore neck along with
numbness in palm and legs. Also associated with
nausea and weakness, itching at neck level.
I suggest all this symptoms can be due to couple of causes like
spider bite, or
dust allergy, or neck issue related to spine, or generalise weak immunity and health.
Now here you need to check is this happening every time you do cleaning of dust then it can be related to allergy with dust, if its there from long time along with
neck pain then it can be due to issue with
cervical spine and i suggest to visit orthopedic doctor for proper examination and treatment. And in general if you always have one or other health issue means your immunity is low for this you should take regular multi vitamin and multi minerals along with balance diet and regular exercises. If there is a issue with spider bite then you need to take anti dose and need to visit doctor for it.
You can also use
cold pack at your neck level for some more pain relief. As well do check your blood pressure and sugar level. And do symptomatic treatment if needed.
I have given here generalise guideline but I suggest to visit a doctor for proper examination and diagnosis if it is not becoming well. And take needed treatment.
Take care.
