Goosebumps in weird patches randomly,

It's been 5 years in total I am suffering from this,i suffered from a very strong headache one day(dk if this links to it or not)..then after some days its been on the increase,i feel my head and neck became stiffy and filled,,its really hard to explain this,not even 1 sec in these years I felt good,only signs I see are some goosebumps randomly on any part of body in patches,sometimes on head and leg at the same time,the main problem is I ve experience very low mental performance,I just cant concentrate on anything,,I feel something moving around my scalp ears,,face sides etc,in.the first year it was increasing day by day,,then I am seeing improvement over the period of time,but it's very slow,,it's already been 4 years and I still feel this,I can only see some weird goosebumps randomly on leg,hands,face in patches,doctors haven't found anything,,My MRI was correct and some other tests too,,then doctor gave me some anti depressants,I took them for 6 months but no gain
