Weed withdrawal symptoms ?

I have been smokng weed for abu 4 to 5 years eavier in the ast 2 yars and suddely just quit. This has left me wit a few withdrawal syptoms. At first i had a strange felling all down one side of my body leading me to think i was going to have a stroke, i felt like I was going crazy in the head and it always used to be worse at night. I found it very hard getting to sleep and would be awake till early hours of the morning till I finally feel asleep but I wake up after a few hours and then hit would take me about an hour to get back to sleep again. It made me very irritable and I got angry easily. But after about 3 months all these symptoms went away and I felt better. It has now been about a month since all the weirdness has gone until a few days ago when I started getting the weird feeling in my head although it does feel like a pain its just a strange feeling that won’t go away and this time instead of feeling I’m going to have a stroke I’m convinced that I’m going mental. Are these symptoms of with withdrawal and if so is there anything I can do to get rid of them?
