I recently had osteomyelitis and had seen doctors within a week of diagnosis, do i have a case?

I recently developed osteomyelitis. 4 days before diagnosis, I went to a doctor due to being in severe pain and swelling in femur/knee. The doctor completely dismissed the pain and wouldn't even give pain medicine while in agony. That day my blood pressure was 180+/135+ and the doctor did not notice or mention this before sending me off with a prescription for physical therapy. 2 days later, the swelling increased and became red along with my knee being immobile. I went to an urgent care center to get pain medicine. The doctor there thought it may be Cellulitis and wanted to do and ultrasound (which I declined at the time) and released me with a prescription for pain medicine after doing bloodwork. I followed up with a orthopedic 2 days later (only doctor that would take me) and had a severe bone infection requiring emergency surgery the next day followed by 10 days in hospital. Infection resulted due to untreated root canal after ENT recommended sinus surgery instead refer dentist.
