thanks for your question
when you press on your left side do you feel any pain?
any shortness of breath, cough or fever?
Yes pain, but like a bruising type pain, not a stabbing pain. No shortness of breath, no cough, no fever, no vomiting or diarrhea. Just the pain, going on for 3 days now. Starting to get concerned.
did you do any heavy lifting or stretching?
it can still be muscle sprain from sleeping posture
you may give a trial of anti inflammatory medication like ibuprofen
apply heat pad
this can be triggered from nerve pinching
intercostal nerves run through the area
they may get pressed during sleeping in a particular posture for long time or mattress problem
in the absence of other symptoms, the differential diagnosis is pretty much it
Have tried the ibuprofen. Thought maybe it was intestinal of some sort, but it's not going away. It's not unbearable, just uncomfortable.
