Flight Attendant reported a hard bounced landing which caused the Flight Attendant back and hip pain.

Narrative

Severely hard landing. Landed hitting hard; bounced; and landed a second time extremely hard. Latched compartments opened; sodas and water bottles flew out; my link flew out of my trouser pocket and hit me in the left eye. FA wig flew up and fell on the ground. We both flew up in the jumpseat despite being fully belted in; and then jolted back down into the jump seat. It was horrible. Thought we were crashing. We taxied to the gate and I went on the speaker to say if anyone needed medical attention for any reason to press their call lights; so we could call medical to the gate to which no one did and when we got to the gate nobody requested medical. One woman getting off the plane demanded a refund on her flight because of stress and said she felt like a disc had been shifted in her back; and when the gate agent offered to call an ambulance she refused and said she just wanted the airline to cover her medical bills; not send her to the hospital. There was an airline pilot and a line check airman jumpseating in the cockpit; and they left very ashen in the face. Captain came out of the cockpit and immediately went to the lav. He stayed in there until half the cabin was deplaned; and then left without debriefing. I was in shock for majority of deplaning and didn't feel the stress on my spine; but after getting in the van my lower back and hips ached despite taking a Tylenol. Next day back and hips still ache; despite Tylenol again. No calls from any supervisors.
