Long story, short version - pain in arm for several weeks, elbow, wrist, forearm. Had a scan, bursitis in shoulder. Shoulder itself doesn't actually hurt, tho tender to touch. Had a steroid injection in shoulder on Tues, have physio booked for 2 weeks time. Today I'm going out of my mind with the pain in my arm - wrist, hand up and down arm. Just want to curl up and cry then sleep. Taking ibuprofen and paracetamol. Also having pregablin because at the same time have sciatica in opposite leg (bldy wreck.) Anyone on here had steroid injection, would it have started having a effect by now (3 days?) Painkillers doin nothing and I'm struggling with it.
