Dolor de hombro no diagnosticado

Severe pain in shoulder which goes down arm and into hand. Also in neck. Limited arm movement. This all started following an injection for hayfever back in March. The injection was very painful and pain in shoulder, neck and arm has not gone away. I can find information on Shoulder Injury Related to Vaccine Administration (SIRVA) but this seems only related to flu vaccination..has anyone else had long term problems following an injection into the upper arm? Ultrasound shows a small tear but dr...says not enough to axplain this extent of pain. Have had 2 cortisone injections...did not help. Have been on various levels of pain killers and juts started a pain patch...no relief as yet. Having MRI later in the week. Would love to go back to specialist with some questions and maybe suggestions....seem to be getting nowhere. Any suggestions will be greatly appreciated.

¿Dónde está la lesión? ¿El nervio axilar? Los Centros Nacionales de Información Biológica tienen estudios sobre el tema, la Dra. Susan McKinnon (¿sp?) de St. Louis es bien conocida en el campo de la reparación nerviosa. Hay numerosos videos en YouTube. ¿Quizás sea un tendón dolorido o algo así?

Thanks terry555 not sure exactly where the tear is..really waiting to see what the MRI shows. It is my 60 year old brother who has the problem. He has cerebral palsy and an intellectual disability...usually has high tolerance to pain but this seems extreme and has been going on for 6 months now. He usually goes to supported employment each day but has not been able to do this...'work' is also his social life so he is also becoming isolated, except for family. It is so hard to see him in so much pain.

Eureka,

Tú y tu hermano merecen algo mejor, y espero que llegue pronto. Los resultados de la resonancia magnética podrían arrojar luz importante sobre la situación.

Todo lo mejor,

Thankyou so much for your messages...will let you know what results we have from the MRI.

Hi Eureka,

Is there any update you can share with us?  I got a flu shot about 1.5 months ago and am dealing with shoulder issues now.

Thank you!
