Hello VHDude78 and welcome to NeuroTalk.

Sometimes those with MS can have an increase of pain due to heat, being sick, or over doing it. Those things don't trigger the pain, per se, but can increase what we already deal with.

Neuropathic pain (nerve pain) is treated differently than other types of pain. Over the counter pain medication will not help neuropathic pain (per my neuro and my own experience).

If I have pain and I take an over the counter pain reliever it does not touch my Neuropathic pain (MS pain) but it does help when the pain is not related to neuropathic pain/MS.

What come to mind by your description is what is referred to as Lhermittes sign. This is when you bend your head down (not your body), chin to chest. You can have abnormal sensations such as buzzing/vibrations, electrical shocks and tingling from the spine down, although some feel it from the waist down. These sensations will only last seconds but can be repeated each time you bend your head down.

If what I described does not fit what you experienced then you are not experiencing lhermittes. If you are experiencing lhermittes there are different causes for this to happen. In Multiple Sclerosis lhermittes is caused by damage (lesions) on the cervical spine.

Although MS can affect the spinal cord the fact that you do work out quite extensively makes me wonder more about a spine injury rather than MS. Although MS could certainly be a possibility. Many other conditions would also need to be ruled out as there is no symptom which is unique to Multiple Sclerosis.
