Hi. My sister is 31 years old and she's been having chest and arm pain since October. She drives a school bus. Her chest and arm is having muscle spasms, as described by her they feel like labor contractions.

She's been tested for lupus, arthritis, MRI, stress test, cat scan for lungs and heart. The diagnosis was swollen ligament bursae?? not sure of spelling but they said her shoulder was swollen in three places. they also referred to muscular skeletal but she's not sure what this means.

She is wondering how long do muscle spasms last and if she was diagnosed correctly? She is going to physical therapy and they have her doing exercises no massaging. I told her to stop driving the bus and let her muscles rest but I'm no doctor.

Does anyone have any advice??? Thanks in advance.
