What the heck is going around? Need cheap urgent care

Like most of us I caught whatever illness is going around. It’s the worst I’ve felt since covid. I’m wondering if this is covid or the flu. I’ve been sick since Monday and each day I get worse. I’m running out of sick days and I’m in between insurances at the moment. I went to urgent care to get a Drs note but it’s $250 and then my work said a drs note wouldn’t even matter so I didn’t bother getting checked out. However I’m soooooo sick I think I need to get anyways and get meds.

Does anyone know of inexpensive urgent cares? In Huntington Beach area would be great but willing to drive further.

Thanks you and stay safe everyone!
