Hello everyone, maybe someone had such experience At the bottom of the abdomen, there are tingling sensations, periodically on the forehead, they also manifest themselves, especially when walking... Today I couldn't fall asleep for half the night, my stomach hurt, it was hurting... Is this serious? Should I call an ambulance or go see a doctor? I'm afraid to go to the doctor, they will probably put me in the hospital...and they told me at least a month to work out completely, without sick leave.
