Suggest Treatment For Pressure In Left Arm And Shoulder While Having Spinal Arthritis
Most likely degenative spine disease.
Detailed Answer:
Hello and thanks for using HCM.
I have read your query and understand your concerns.
In my opinion, first condition that may cause your symptoms is degenative spine disease and its related nerve(s) compression.
Since the discomfort you describe spreads to left arm and shoulder, heart condition should be evaluated too as a possible cause, but it is very unlikely, since symptoms worsen with rest and depend from arm position.
I suggest you to consult your primary care Doctor about your concerns and to discuss about further tests to determine the diagnosis.
In my opinion, there is need for a neurological examination and imaging studies of your cervical spine such plain radiographs and MRI.
Hope you found the answer helpful.
Let me know if I can assist you further.
Take care.
