I have studied your case with diligence.
Due to fibromyalgia
there can be degenerative wear of muscles and ligament and loss of elasticity of muscles, due to deficiency of VIT B12 and carnitine these symptoms can be aggravated .so supplements of these nutrients can relieve pain.
Some biologic medication like anakinara or infliximab
can be started,
I will advise you to do regular physiotherapy
and exercises as my patients find much relief by these therapies.
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.
