I completely understand that all of these symptoms you are having are real. I understand how hard it is to deal with anxiety due to your health and wellness. But at least for me, the more I focus on aches and pains I may feel from time to time, the more anxious and depressed I get. Your doctors would not lie to you. They understand how desperate you are to finding out some sort of conclusion to these alarming symptoms you have been experiencing. Like Rich99 stated above, trust what your doctors are telling you. Pains of any kind can be tremendously scaring and alarming, especially when they can seem so crazy. But take all the advice you have been given. Try your hardest to relax some and get your mind focused on other things in your life. The more you sit around in constant fear and worry, the worse you are going to feel; emotionally and even physically. Try to keep your composure. Best of luck to you in your recovery!
It all sounds like it began when you first started concentrating on your physical sensations which caused some anxiety which then in turn caused you to notice more physical body sensations.
So to point you in the right direction I will urge you to trust the results of all your medical exams and lab work, and then begin to let go of watching your bodily sensations and put your focus on other things in life that you enjoy doing.
you have had every test under the sun to rule out your worst fears,and have all come back normal,everything you are going through can be caused through stress and anxiety,and you sounds like a classic case for it,you have convinced yourself that you have ms or parkinsons,which is making your sypmtoms a hundred times worse,you maybe do need to go and speak to someone,learn some relaxation technics,and stop reading these books that you have been reading i always used to go on the net to search for answers to relate to my symptoms and it just screwed me up bad.
