hi i go to bed and sometimes i strugggle to fall asleep straight away and still wake up approx 2a.m or sometimes i fall asleep straight away and wake at 2.a,m . My upper thighs can be painful where i feel like stabbing them, i will be awake for about an hour and half and eventually get back to sleep. i had my gall bladder out 10 days ago and i had this problem before but i,m sure it's worse now cos it's every night. i have a low blood pressure naturally but it's not dangerously low, but it's always mentioned when i get my blood pressure done
