I could do with some help, ... advice, if you like.

For a long time, I've had a sensitive head, which I later discovered to at least partly be due to Filloculitus. Still, it's not just the scalp, it's inside the head, too. Lying on my back has been a problem for a long time... well, in particular, lying the back of my head on something... it just... feels horrible. I wish I could explain it better, but I'm too focused on what's going on right now.

Right now, I'm freaking out and tempted to call 999, but I can't figure out if I'm being "OCD" about it or not. I have mild nausea, feel dizzy. The back of my head... well, if I stroke it, it makes it worse... I can't explain the feeling... I first noticed it when I had a shower a few days ago, maybe a week or two.. ran the water from the shower head on the back of my head to my neck... it felt what I thought was amazing.. absolutely amazing.. like, can't explain it... maybe like a muscular thing... tense muscles relaxing or something.. IDK. Anyway, that happened at least 2 more times. Today being one. I don't feel right at all. I text my dad, and told him, but I don't think he got it. I can't ring him, because no credit. There's nothing I can do except 999.

I'm on Lymecycline (1 a day) for the Follthing, and using a prescribed cream on my head that I can't remember the name of. I occasionally take Propranolol, as needed, for the anxiety. I took 1 Ibuprofen today, but really, it's not often I take them. I took the profen because of this, basically,.. just got progressively worse through the evening... or morning, since it's almost 4am. (yeah, I'm also very tired.. but now I'm scared to go to sleep in-case I clock out)

I feel like I'm drunk or hungover... but I'm aware more than if I actually were drunk. My HR is 56bmp. 'o.O Jesus, Christ. I've never seen it that low. Last I checked, my resting was around 60-70 or something. I workout a lot, eat healthily. (recently started fasting, yesterday was one, Monday was the other I think... other days are normal but caloric deficit - 2000kcal.. I'm 6ft 183lbs)
