So worried :(

[TreacleMoon123]

This is a bit of a long one so bear with me if you can. Last Christmas I started experiencing anxiety and panic attacks. Up to this time I had felt perfectly healthy. I started taking 5mg Lexapro last march. I had awful side effects getting established on it and i never felt 100% while on it either.
I started experiencing a hot/cold sensation in my feet which travels right up to my thighs. I also had what felt like a tightening in my cheeks. I felt they have may have been side effects of the Lexapro so I came off them about 2 months ago. But I am still having these horrible feelings, along with neck pain and a headache at the back of my head.
I've seen my gp who did some routine neurological checks and said everything seems ok. She wants me to wait awhile before sending me for an MRI.
I'm sick with worry over what it could be.
I can feel the panic starting to creep back in..

Hi there Treacle,
I'm no doctor, but I would guess that part of the problem is that now you have come off the tablets, the anxiety is returning. I would ask the GP if you could try another medication to deal with that whilst you are waiting for your MRI. You shouldn't be left this anxious. Definitely go & ask for something else. The MRI will show if there is any physical problem, but you also need help with the anxiety & panic.
One other thought, you said it started last year at Christmas & this year its the same - it could possibly be a 'SAD' type problem? Good luck.
