### input:
I have sharp pain (not constant~comes and goes) in the middle area of my left shoulder blade. Have had herniation repair at C5-C6 about 4 years ago, which still can present occasional discomfort at neck, or back of shoulder blade region, or upper left arm ache. But this fairly recent (months) nagging, panging pain through the center of whole left shoulder blade area feels different and I am concerned about referred pain from some organic problem. (Heard on a TV ad about a woman with pain between her shoulder blades who had advanced pancreatic cancer~scares me to compare my shoulder blade pain! How should I research this? Shoulder MRI? What do I do? Recent extensive bloodwork with primary care physician (which we check occasionally) had NO flags other than a bit high A1C count. I get frightened because my sister passed away 2 yrs ago with lung/liver cancer (non-smoker).

Hello, I have studied your case. You can do MRI cervical spine and shoulder and PET scan for diagnosis. Due to recurrence of cervical nerve root there can be tingling numbness in your arm and shoulder. For these symptoms analgesic and neurotrophic medication like pregabalin and methylcobalamine can be started. Till time, avoid lifting weights. Continue your Physiotherapy like ultrasound and inferential therapy will give quick relief. I will advise checking your it B12 and it D3 level. If nerve compression becomes symptomatically severe then surgical decompression will give permanent relief. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care.
