hi there ! for the past 4 days ive not been sleeping well at all and been having severe nightmares . yesterday was a bed day pains were bad but today i have had the most perculiar thing happening in my head its been fuzzy and i keep getting sudden wishing sounds of my heartbeat in my head and also my eyes are hurting from behind, also i went to the shop and i had the feeling that i was going to pass out or something . im not stressed or nervous being in shops so it cant be a panic attack but i really feel like somethings not right.also i have been having mega tingling in my hands can anyone enlighten me??
