I have chronic pain at a particular spot in the right tricep, right where the deltoid ends. Hope that's clear. So that pain has been consistent for like four months, and it causes pain every time I move my right arm, right in that very spot. While doing yoga, and while sleeping, severe pain when I lift my arm vertically to the ground. But two days ago, I noticed a greenish bruise at the exact spot it has been paining all this time. And now my AR is weak, I can't work on my computer for long hours because of that pain, I can't lift things without an ouch. Is it a cause of concern, what can be done about it?
