Hello everyone. New member here. Please bare with me as this is gonna be little bit long.
Im 31 years old. I dont drink and smoke. I just wanna share my experience and situation and all the physical stuffs that im feeling since 2013. It actually started when i was taking a contraceptive pills. I observed, since i was taking that pills, i became more tense and easily get nervous. Ive been taking that pills for atleast a year last 2012-2013. And last May (2013) when i am havibg first day of my period, i began feeling and expereincing all these debilitating symptom. Suffered from very bad palpitation (100-136) chest pain, seems like im going to pass out and all, dizziness, pain in stomach, constipation, hypervjntillation, numbness in my legs and arms, cold extremities, losing & thinning a bunch of hair, sometimes hot flushes. And so on and so forth. I went to alot of doctors, Neurologists, Cardiologists, Rheumatologists, ENTs', Hematologists etc... They did lots of bloodworks and imaging tests (MRI, CT Scans, chest xrays, ECGs, 2D Echoes, Duplex Test) But THEY CANT FIND ANYTHING! 
My ENT and Gastroenterlogist diagnosed me with GERD and IBS and they gave me medicines for that. It helps my GI Tract symptoms and all but not much. My cardiologist diagnosed me with PVC and PACS and im under medication. He gave me Ivabradine 5mg three times a week coz i cant tolerate the side effects ( dizziness, fatigue and weakness. Sometimes diarrhea). It somehow helps but still feeling the same. I also went to a rheumatologist to check if i have autoimmune disease but he diagnosed me with Fibromyalgia. Went to Hematologist to check my blood amd iron, ferritin levels TIBC etc., because i develiped anemia and after all the blood works, she diagnosed me with Iron Deficiency because of my period. I even tried to asked her is shes sure my anemia is not because of any chronic illnesses (autoimmune or cancer) and she said "NO" because of the results of blood tests. I went to Neuroand did some CT Scan and MRI of my brain and spine because i often have headaches and back pains and numbing and tingling in my arms and legs and sometimes all throughout my body. I also did some nerve and muscle test but all they flund out was a slight cervical injury (neck) and Lumbar radioculopathy (hips). My brain MRI was normal and they cant find anything. They checked my thyroid tol and everything is normal. Still im feeling the same no matter how much i convinced myself that ive been thru alot of doctors and did lots of tests but they cant find anything. They always tell me to go and see some psychiatrist but eversince, i havent made any appointment from any psych because im convinced that I AM REALLY SICK. I tried to ignore those physical symptoms and i was fine from 2014 till early 2017. BUT, my symptoms appeared again just last month this year. (novmber 2017) up to now. I feel horrible. I cant go out even if i want to because im scared. (Though sometimes i can manage to go and get some groceries or buy something in a short span of time and of course with someone to accompany me because im really scared that i might pass out and all.) But lately, i cant tolerate to go out. :'( i am so scared with same reasons again and i observed, when im in malls or grocery stores, i get dizzy and starting to get cold sweats and always run to the comfort room to poop. Its always been like that. And i cant walk much because i feel weak and dizzy. Like fainting. Two weeks ago, i also had some panic attack as my heart started to beat so hard and i feel nauseated and my whole body was numb and cold and i feel dizzy and i feel like im going to pass out or die. But i didnt. Everytime i feel that way, i take Ivabradine and it makes my heart go slow and i feel so weak after that. Actually this launch i had panic attack again and was crying so much. I dont know whats happening. I cant even sleep nicely. And i always feel uneasy. Almost everyday. And also, i feel pressure and pain in my chest, shoulder, back, neck and my head. And everytime i burp, i feel comfortable again. Then for few minutes, it will feel the same again. Is it acidity? Because i have hoarseness sometimes as well as regurgitation. Not often though. And my symptoms usually gets worse when my period is about to come or when im having my period. (Maybe because im anemic??) Please help. I really dont know what to do.
P.S. thanks for ur time reading.
