Brief Answer:
Myelopathy

Detailed Answer:
Hi,

thanks for your question.

I'm not sure that all of your symptoms can be related however I am concerned about the weakness that you describe and loss of balance / coordination in your leg.

This can be due to a myelopathy which is compression of the spinal cord in the neck by a prolapsed disc or other issue.

The diagnosis can be made by a thorough physical exam and an MRI scan of your cervical spine.

I hope this helps answer your question.

Best wishes

Sexual arousal, especially orgasm, (see section to follow)
Inflammation (for example, caused by allergic reaction or infection)
High doses of non flush free niacin (vitamin B3)
