Possible arthritis after DKA?

I was hospitalized in early May due to DKA, as a type 2 diabetic, caused by medication (Jardiance). Spent 5 days in the ICU, ketones were 6.9, have no memory of 3-4 days. It was a rough time. After being released from the hospital I was told I may feel weak and would need to build strength again. It’s been going well, except I am sore. Like can barely move when I first get up (from bed or just sitting), very very stiff. The diabetic clinic seemed concerned this afternoon and they booked me for an appointment with the diabetic specialist for two weeks times, a rushed appointment as they are booking her regular appointments for the end of October.

They suggested I take Tylenol Arthritis for a few days and stop, to see if there’s a difference. In two weeks time, they will determine if further tests should be run.

Has anyone experienced this? What helps you with stiffness?
