Why am I feeling tight around arm?
Patient: About two weeks ago, I woke up and found my left arm feeling tight, like I pulled my muscle.  If I straighten my arm, it feels tight.  Feeling along my arm, I found that the discomfort was really originating from my vein; and there were a few bumps (4 or more) along the vein.  What is this? Doctor: The pain by your description looks non cardiac. Still, to rule cardiac cause tell me what is your age. Any associated disease like diabetes, hypertension. Smoker or not. Get a ECG done. You can get a TMT or stress echo done for cad risk assessment. Get back with the answers.Dr Sameer Maheshwari
