For the last two months I've felt completely ill and have been routinely visiting the hospital. The first time I went in was because of what felt like liver or gall bladder pain, after being scheduled for an ultrasound i went home and arose in the morning with pain in my sternum. After an ECG, chest xray ,and ultrasound, i was given a misdiagnosis of GERD (havent experienced anything like heartburn since). I persistently worried about this, and a day later i had developed a muscle twitch (generalized/not confined to any specific areas.) Within the rest of that month, I developed fatigue, muscle pain, intermittent nausea, vomiting, diarrhea, constipation, headache,sleep problems, loss of balance, along with the persistent muscle twitch. My mind immediately went to the worst of diseases, mainly those in the categories of neurological and autoimmune. During an exam(current Food & Nutrition student) I had a panic attack. Following this I went into the emergency room where I saw crisis intervention, and was given a prescription of clonazepam. In the following month while taking the clonazepam, I still felt the same symptoms as well as the development of new ones, ie; swollen submandibular lymph node, easily fatigued after physical activity, heart arrythmia, palpitations, sore joints(especially hands and feet, and elbows), a vibration feeling when waking, excessive sweating (hands, feet, armpits). As a result of all of this, my anxiety has worsened and I feel completely depressed and hopeless. I have a follow up appointment for the blood tests(TSH, Monostat, RX, Calcium, Magnesium, A1c, Creatinine, CPK) and EKG that i had conducted. And i have booked an EMG in early April. I can't help but to worry about all of this. I'm not sure if this is all anxiety/depression related or something far worse. Any insights?
