What Causes Cramps On Entire Head?
Read below
Detailed Answer:
I read your question carefully and I am sorry about the symptoms you are experiencing.
First of all the type of pain you describe and its location nature is not typical for any brain lesion like tumor, stroke, infection etc, so there is no motive for excessive worry.
Now, what could it actually be. One condition which produces moving, short lasting pain is primary stabbing headache. As the name suggests patients describe them more like stabs then cramps, but there can exist variations. They have no known cause, usually do not require any treatment as they end up too soon, but if frequent and bothering to the patient can be treated with Indomethacine taken daily.
Another possibility could be neck muscle tension radiating into the scalp muscles, can be triggered by cervical spine issues but also by stress or anxiety. Usually over the counter pain killers like Ibuprofen are effective.
For the moment since as I said these type of pains do not suggest anything serious and it's been only two days, I wouldn't rush into unnecessary tests. Would try relaxation methods, light exercise and Ibuprofen.
I remain at your disposal for further questions.
