Its not clear whether your symptoms are neurological or not - typical neurological symptoms result in weakness, clumsiness or loss of sensation on one side of the body, loss of ability to see or speak etc
Tingling down the back that is precipitated by neck movement, associated with stiffness in the leg muscles could potentially be from a spinal cord problem - the neurological examiantion should reveal more, and somatosensory evoked potentials of the posterior tibial nerve might be used to investigate this.
Otherwise, there may be a more rheumatological flavour to your symptoms
Have you seen your doctor? the best place to start is a thorough physical examination, then your doctor can decide which alleyway to follow in terms of further investigation.
The headaches could be from a whole variety of causes - I cannot tell from what with just the above information but headaches can be from a more systemic medical condition (for instance rheumatoid arthritis or ankylosing spondylitis - possible rheum conditions in your age group) - in which case they need to be investigated promptly.
I suggest seeing your doctor as soon as you can to follow this up
Good luck
Have you taken any antibiotics within the past few months?
Why do you ask?
I have had the same problem.
3 MRI's, just had a spinal tap, they've suspected MS but the CSF showed negative. I've been through test after test. There is a adverse effect of neuropathy from the family of antibiotics that had taken.
This has been happening to me since July 2004.

July 2004 I started having electrical sensations in the middle of the night. For a year and a half anytime during the day I get a electrical shock type pain. I have edema, I've been through every test they can think of, 3 different neuro Dr's and still no diagnosis. I can't pull a wrapper off a straw, I have problems writing.
All started from the Ciprofloxacin;
This is a KNOWN adverse effect from Bayer. It is irreversible, and still to this day with all the people effected by these drugs, the Dr's still don't believe it. Check out this info.
