I have constant pressure in my head. Its weird and I dont know how to call it but I feel like my brain is twitching. It feels like somethings weird with my nerves and it happens every 30 seconds. Its in the front part of my head. This has been going on ever since I overdosed on antidepressants and antipsycotics so I dont know if thoose meds did anything to my brain? I now have nausea and I don't know if that plays together with it but I thought I'd tell you all that I'm feeling. Please give me any information. Thanks in advance.
