Detailed Answer:
Hello
Thanks for writing to XXXXXXX
From history, it seems that your husband's swelling is chronic in nature and such chronic cases are generally benign in nature.
Firstly he should be properly examined and investigated.
Most cases are diagnosed on clinical and imaging basis.
Biopsy is not needed in most of the cases.
Swelling may be due to lipoma,
dermoid etc.
CT Scan(Brain) may be needed to confirm extension of disease internally.
So,you should consult surgeon.
Other physical problems like
neck pain, earache and generalized weakness is not related to swelling. It is due to other reasons. It needs to be investigated.
He needs investigations like routine hemogram,RBS,LFT,
Lipid profile,RFT.
For neck pain,X-ray
cervical spine (AP/Lateral view) should be taken.
For earache he needs ENT consultation.
Get well soon
Hope i have answered your query.
Further queries are most welcome.
Take Care
