Hey Fubar,
Hope you find this since the topic got moved. I have learned through this whole experience that when a doctor refuses to test you for something then you have every right to demand it. It is your money and time.
I noticed my symptoms about 6 months ago. One night I was getting out of my car and thought I had put my left arm through a spiderweb. I kept trying to get the web off of me, but realized there was no web at all, instead I was having that sensation. That nearly made me pass out and throw up from fear and anxiety.
Since I have been getting my b12 injections, that sensation has gotten a lot better. I occasionally get it on the face, but have not had it on my arms in at least 3 weeks (knock on wood).
It is weird because I have always had bouts of anxiety in the past for like a month here and there...and health anxiety has always been my main problem, but this is the only time I have not been able to shake it at all. That is another reason I don't want to go on serious meds yet, because I have not had this my whole life. I want to see if I can regain control myself by trying other methods, like vitamins and maybe CBT before I take something so hardcore.
Having a b12 deficiency and other vitamin deficiencies can also cause and enhance depression and anxiety, so I am going to wait to see if I continue to feel better on my own, which I have already started to do. Your body stores b12 for like 4 years so it takes forever for a deficiency to show up.
I think before you decide to go on meds, just have some blood work done to know your vitamin levels, your blood pressure, cholesterol, glucose, thyroid and other normal stuff. You might find your anxiety is heightened by something in your body.
Also be warned, my doctor told me the only side effect of paxil was feeling hyper. After 2 days on paxil, I felt like I was going to die so I googled it to see other initial side effects and realized the medicine was too hardcore for me overall. I definitely can understand how people need it and I might need it one day, but I am not ready for that commitment yet.
Please let me know what you decide to do or what your doctor "allows" you to do. I am so curious now. I just hope neither of us have to deal with that sensation at all for much longer!
