I am not a medical person. The pain in the left arm can be a sign of heart attack. It is said that females have different symptoms than men. The bruise must be coincidental. A visit to the doctor is advisable to let them check your heart and blood pressure. If you get the bad left arm pain again, go to the emergency room.
Last Night I Woke With Excruciating Pain In My Left Arm. I Took 6 Ibuprofens And Pain Subsided. Today My Arm Aches And There's A Small Bruise On The Left Side Of My Ribcage. Is That Heart Attack?
It seems to me that you where possibly attacked in your sleep, I would beat up my mates during sleeping it would be a oneway fight. My mate is a hard sleeper and have awaken to some type of strange pain and lite bursing? But please play it safe and go to the doctors and have your self checked. I would take may mate and never owned up to nothing.
