hi welcome to HCM
-hi i had gone through your query and understand your concerns.
-there are several possible causes for your condition but most likely , i would come up with two most possibilities to fit your condition .these include
1.the first one may be PERIMENOPAUSE or MENOPAUSE;due to hormonal
imbalance in this condition.
-hormonal assays may confirm the diagnosis
2.the second possibility is,CERVICAL SPONDYLOSIS;due to degenerative changes in the cervical spine
are the possible causes
kindly rule out the other possible condition like DIABETES;check your blood sugar levels may confirm the diagnosis
I hope this is helpful for you, thank you
