I have a heavy full pain in my upper right arm that has been there on and off for a couple of weeks. ibuprofen had relieved it but not today.

Right upper arm pain: Follow up with doc. It could be musculoskeletal/nerve from neck issues( c- spine xrays or MRI), or shoulder issues ( xrays or MRI) or alternatively lymph nodes in the clavicular area or even from the breast.( xrays of chest, exam, mammogram), or vascular vein compression. At 54 you need a full work up follow up w/ doc this week

Right arm pain: Pain that has been present for a couple of weeks warrants evaluation. This could be infection, musculoskeletal or lung or hear.

Get seen: Pain that is lasting this long and evidently getting worse not better should be seen by a Dr. Based on your brief description, the range of possibilities is quite wide. Could include a problem with the shoulder joint, referred pain from your neck, referred pain from your diaphragm or worse, referred pain from your heart! A detailed history + exam with a GP is advisable.

Needs examination : To work out if shoulder problem referred from neck/pinched nerve or other (heart /angina is a possibility here)and if cause unclear will need tests done
