i have got burstitis in my shoulder. i have had a cortozone injection that the doc gave me. but after an ultrasound he said it didnt go where it it was suposed to go. so i had to have an ultrasound guided steriod injection . i was told to keep my arm in a sling for two days which i did. but it was getting really stiff after two days so i took it off...i feel more pain than before so i will be seeing the doc again..the guy who gave me the steriod injected said i can go swimming after two days when i take the sling off, i might wait afew days first before swimmming and see what the doc says first. If you have had it what treatment did you get?.
