Soothing pressure in head and over body

[Earthboy]

Hello there in my doubtful world of mind where lot of things going on. I have been meditating for 3 years and I have been getting this pressure which is hard to get rid of, it always stays there like a wire electric feeling floating and takes me off my presence and into feel of the pressure. It is not painful but annoying sometime because I like to feel like I used to sometime on my own going to bed or lying by myself or meditating. It keeps popping and play around my forehead making like electric movement over my body. It's been going on for about 2 year and still happening. I haven't seek medical help coz I don't think it's wrong, I just want to be able to control and take the joy out of it. If anybody have such issues feel free to share and let me know how you deal with it
