Thanks for the detailed description of your query.
Function Test (LFT) is slightly deranged from the normal. There is nothing to panic about it and as such no immediate management of it is required.
Repeat the LFT after 3 months and check for the results.
Your Lipid profile
seems to be deranged and is concerning. You must start right away with dietary change and lifestyle modifications including exercises. Get an ECG done too. It seems like you may require lipid lowering agents (Medications) too for this.
The cervical spine
x-ray shows changes as you mentioned. But nothing needs to be done surgically for this as of now. You will benefit by physiotherapy
and neck exercises.
My suggestion to you is to get back to your primary care
physician and seek his guidance about the management plan.
Hope you are in fit health at the earliest.
