Waking up from sleep crying because my knees hurt THAT bad. Have osteoarthritis and bursitis in hips. Idk whats cuasing it?

Severe pain. I'm unsure as to whether your primary joint problem is simple osteoarthritis and ordinary hip bursitis because of the severity of your symptoms. I highly recommend a consultation with a rheumatologist for diagnosis and treatment. Appropriate tests and xrays will be ordered.
