Hi I'm a 21 year old female and was currently told by my doctor that I may have some anxiety issues. He put me on 50 mg of sertraline and I take it each morning. Let me just start from the begining of my anxiety journey... About 3 years ago I had my first panic attack, probably the worst by far! I was shaking, my heart beat was insane, and I had feelings like I was going to die or faint. Then for the next few monthes it seemed like i would have frequent but not as bad of attacks more easily. Now its three years later and I started to have throat and chest pain, along with some more panic attacks. The doctor said the way i described the pain it sounded like acid refux or heartburn. During the check up I had also complained about some upper back and neck pain. He had me lay down to feel my back and said i was very tense. He went ahead and performed some minor manipulations to my back and neck before i left to see him in 3 more weeks. So day 2 after my visit, I was lifting my head to look above me and as i adjusted it back forward i had this awful hot, weak sensation on the back of my neck, it lasted for maybe 3 mins. The next morning I woke up and my neck and the upper side of my head felt tingly. Throughout the day I worried myself and it felt like the more concerned I was about the tingling the worse it had gotten. Soon my back and right arm were tingling off and on the next few days...then some more days past and I can say the tinlging was just happening anywhere and everywhere on and off, for example my pinky on my hand for a few seconds then my hip then my foot, just on and off in just about anywhere on my body. Also note I havent felt well latley, I get feelings were I felt dizzy or like I was going to faint, almost feeling like I was always on the verge of a panic attack but it didnt happen. When I went back to my doctor I told him about the tinlging and I asked if it could have been a side affect from the maniputaion and he said "no". This worried me even more but he told me that anxiety can make you feel many skin sensations such as the tinlging i complained about. I went on with taking the sertraline and I seems to be helping me out with the dreamy feelings I get during the day, and I havent had a panic attack since the meds. The only thing that continues are the tingling/numbness ( mostly in hands, arms, feet and legs now) I wake up trembling, sometimes just my legs and sometimes my whole body. It can be internal or I can see the shaking, but it only lasts for a few seconds before i'm completly awake. I can also wake up in the middle of the night shaking. I see my doctor again in 3 days. I have consistantly been on the internet scarring my self, trying to come up with other reasons other than anxiety to why i have these feelings. My aunt has ms, so now I'm scarred I do. I'm scarred my doctor hasnt yet ruled out other imortant medical factors first. What should I do, what do you think is happening to me? Please give me your imput on this.
