Thank you for posting your query.
Your symptoms require detailed evaluation by a neurologist
or a neurosurgeon.
If possible, please send a picture of the bump over the back of neck. It may help in the absence of being able to examine you.
Sometimes, an ultrasound
scan of the bump can give us more clues regarding its nature.
Blood tests such as vitamin B12
level and thyroid
profile should also be tested.
I hope it helps.
Please get back if you require any additional information.
