The last 2 weeks were rough. I’ve been having anxiety attacks almost on the daily and I’ve also been very sleep deprived (sleeping 4-5 hours a night, sometimes even 2) which is also due to my anxiety. On the way, a weird symptom appeared. Paresthesia In the head, a strange tingling sensation that also sometimes feels like pins and needles inside my head. It doesn’t hurt but it’s extremely uncomfortable. I’ve had it yesterday all day long and I woke today with this again. Is this anxiety or something biological?
