I've also been having a horrible headache and bad cramps
Oh and I had general blood work done a couple months ago saying I had low vitamin b.. Which has me believing it could be herpes I don't know why
There is no reason at all to think anything in what you describe is related to herpes. Unfortunately the internet is considered to be 'information' when 90% of it is, frankly, utter nonsense. Make sure you use this lens when reading the net.
For example, muscle twitching has nothing to do with herpes.
For those that need to know, there is a blood test. Pop into your doctor and request a blood test for IgG antibodies type specific for HSV1 and HSV2.
Sorry to bother again... What do you think muscle twitching is a cause of or could be???
Multiple and usually minor issues with the nerves, stress can be a cause.
