First of all, keep in mind that I am unable to diagnose you because I am unable to examine you, this forum is for educational purposes.
The case you describe sounds very complex and there is a lot of data that I do not have. That being said I will try and address some possible causes of your arm pain. Shingles is a reactivation of the virus (Herpes Zoster) that causes chickenpox (that many of us get as a child). Many of us never experience the reactivation of the herpes zoster, but most all of us have this virus 'sleeping' in our nerves. As people age, or when they become sick the virus is more likely to 'wake up'. The virus then causes pain, numbness and itching in a strip along the skin (in the area of the nerve the virus was sleeping in). This is often followed by blisters (which may bleed). When the blisters go away the pain may persist for months or even years. This pain is burning pain at the skin level, but may also cause shock like pains down the arms, depending on how the nerve was involved. There are several medications for this type of pain including neurontin, lyrica and to a lesser degree medications such as elavil, cymbalta, effexor, etc. have been used. I suspect the pain you have is due to post hepetic neuralgia, but some other things to consider include amyotrophy, vitamin deficiency, multiple myeloma and heavy metal toxicity. I would recommend an EMG (I did not see this in your list of tests) of the upper extremities and screening blood work to include b12 level, b6 level, serum and urine elctrophoresis, and heavy metal screen. As far a fibromylagia (fibromyalgia) is concerned this is a poorly defined pain syndrome, that is thought to involve the many areas to the skin and touching causes pain in many 'pressure points'. One theory is that fibromylagia (fibromyalgia) is related to specific sleep problems and getting a sleep study may be helpful.
I AM 59 YEARS OLD. MY MAJOR PAIN IS IN MY ARMS, LOWER BACK AND SHOULDERS. I DO OFFICE WORK WHICH INVOLVES A LOT OF COMPUTER INPUT, PREPARING AND FILING CLIENT FILES, TALKING ON THE PHONE WITH THE STATE COURTS, MAKING COPIES, A FAIR AMOUNT OF WALKING BETWEEN MY DEPARTMENT AND OTHER AREAS IN THE COMPANY.
INSTEAD OF MUSCLE PAIN I SEEM TO HAVE PAIN SPOTS IN THE CENTER OF MY CHEST ONE ON EACH SIDE CLOSE TO THE CENTER, I HAVE TENDER SORE SPOTS UNDER AND ON THE SIDES OF MY UPPER ARMS, ALSO IN MY SHOULDERS AND LOWER BACK. NOT A WHOLE LOT OF THIS TYPE OF PAIN IN MY LEGS. I DO HAVE SOME ARTHRITIS PAIN IN MY KNEES. MY PAIN IS WORSE FIRST THING IN THE MORNING AND AT NIGHT. I START MY DAY STRETCHING MY LEGS AND FEET AND ANKLES BEFORE I GET OUT OF BED I ALSO DO SOME MILD MOVEMENT WITH THE ARMS. AFRAID IF I STRETCH THE ARMS I WILL START MY DAY WITH SORE ACHING ARMS. MY NECK IS TIGHT AND I DO HAVE SOME DEGENERATIVE ARTHRITIS IN THE C5 AND C6. HOWEVER, IT IS NOT ENOUGH ACCORDING THE THE PHYSICAL DOCTOR TO CAUSE MY SYPTOMS (symptoms) IN MY ARMS. I AM NOT SURE ABOUT THE SHOULD BLADES EXCEPT IF I HAVE AN EXTRA HEAVY DAY ON THE COMPUTER THEN THE AREA AROUND MY SHOULDER BLADES GET TIGHT.
THANKS FOR RESPONDING TO MY QUESTION SO PROMPTLY.
