For the past three or four days my right arm has been hurting and feeling weird. I first noticed a weird sensation underneath the arm about a weak ago. The sensation is almost like a numbness wen the bottom of my arm moves across something although if I touch it I fan feel touch there. Also the muscle hurts in my forearm and in the part of he arm from the shoulder down to the elbow but it doesnt hurt all the time,just here and there. My arm also feels weak but I can lift things and hold them and also can hold my arms above my head. I notice the weakness the most when I am typing. I also have a strecthing tight feeling on that side of my ribcage all the way down.I keep thinking its going to disappear if I ignore it but it kind of comes and goes. Its. weird cause verything seems to be on one side. Im concerned it might be a stroke but then its been going on for a few says. Other than this isdue I dont seem to be having any other symptoms,but I do notice my heart beats fine until I get up and move around and it starts skipping beats. I have been laying on my left side for awhile off and on using my right arm to type and do things with but I have done that for a kong time before and never had issues. So im worried this might be a stroke. Coujld this all be muscle strain from unnaturl muscle use or a stroke? I thought the feeling in my arm would be gone after a few days but zi got up to take a shower and my arm really hurt. Im concerned ...does this sound like a stroke? Help?
