I have this ache in my left arm. i feel it in the muscles in front and behind the arm down to my elbow. It is excruciating if i extend my arm backwards (like getting something off the back seat of a car while in the front seat). It is a dull ache otherwise. I first noticed it in March. It has gotten really uncomfortable to sleep on my stomach. I think i hear some sort of creeky sound in my actual shoulder. Just don t know. otherwise i am in pretty good shape. i am 62 - a woman - and in pretty good shape otherwise.
Hi, Considering your symptoms likely cause may be 1. Biceps tendon inflammation 2. Subscapularis tear. Both muscles lie in the anterior part of the shoulder joint and may be affected.  Diagnosis can be confirmed by ultrasound of the shoulder joint. Please get it done from the radiology center nearby you. MRI of affected shoulder is more sensitive than ultrasound. Meanwhile, start tab Attract p twice a day for pain relief. Visit orthopedic surgeon for detailed clinical Examination is recommended.  Hope I have answered your query. Let me know if I can assist you further.
