Severe pain in upper arm

Probably tore or pulled your intertubercular cynovial sheath which runs from your elbow to your shoulder or maybe your deltiod muscle which can hurt up into your shoulder.
Put heat on it which will increase blood flow to help heal. If you have any good sports rub use some in between heating.

Sounds like it. Yes, it can be either of those. You can put yourself in a brace or sling to let it heal and avoid using it. As long as it is getting better after seven days then you are okay. Flex it so that it doesn’t heal in just one spot.

Now if you can’t MOVE your fingers, or wrist, elbow etc…. At ALL … without severe stabbing pain, yes have it looked at. Strains are a thing. They do take rest and weeks to heal, but if it’s dislocated, it has to be put back, if it’s broken, you need a cast. I’m not a doctor, just have too much eesknalbexperience :-(

Could be a partially torn bicep or detachment

Sorry you are in pain.

Same. Constant pain in my upper arms. Chiropractor did the job. Electo-therapy and massage, cracking of the neck, back and shoulders. Took a couple of weekly sessions.
👍👍🤗🤗❤️❤️

I'm still waiting on a rotar tear to get better but I think only surgery will fix it.

You have torn a muscle. Take it easy for a few weeks no heavy lifting or gymnastics for a while.

It can be a spinal disc in your upper back or neck..... I suffer daily .... and that is my problem..... it is MISERY.

tennis elbow, you need to get a elbow support

Did you see a doctor ?

did it begin to hurt while lifting or after?

You need a doc too

Misty, do you have a dull ache deep in the shoulder, Disturb sleep, difficult to comb your hair or reach behind your back, accompanied by arm weakness ?
