weak knees

Zshmara
Hey ladies. I recently got out the military April last year. I have been having the worst problems with my knees. Sore, weak, achy, & hurting feeling. I'm only 24 though! I can't even ride my man like a bike 🚴 🍆😑. What kind of multivitamins or anything over the counter do you guys suggest to get my groove back 💃🕺???
Asking for a friend 😂.
