Thank you for your question. There can be several reasons of such symptoms although without being able to examine you I can not offer you the specific advice on diagnosis and treatment that you need, but I would try to provide you some relevant information about your health concern.
Most likely possibility in your case could be a panic or anxiety disorder that you have faced during last event and currently experiencing. Cause of such panic disorder mostly remain unknown but in this disorder you may feel symptoms like shortness of breath, feeling of choking, pain in the chest, nausea, stomach ache, feeling dizzy, tingling or numbness, chills /hot flashes, bounding heartbeat or fast heart rate, sweating, shaking etc. even without any underlying disorder. This disorder needs to be thoroughly assessed by a psychiatrist first since this can occur repeatedly and without warning. Treatments may include psychological and drug treatments, and depend upon extent of severity of symptoms. Most commonly psychological treatment tried is counseling, relaxation techniques and sometimes cognitive behavior therapy. ************** depends upon treating the underlying depressive illness through anti-anxiety or anti-depressant medicines. In addition, try to rest in a dark & quiet room, meditate, have a balanced diet, regularly exercise and avoid taking unnecessary non prescription drugs to avoid recurrence of symptoms. Hope this helps!!
Please get to a neurologist and have then set you up for an MRI.That way, if there is anything going on up there, you can take it from there, or if there isn't anything wrong, then that will be a large thing you don't have to worry about and it will ease your mind.
I always suggest, and so should your doc, that when you have numbness and insomnia you need to see a nuero ...
Good luck and please have that checked on.
