Help, please

I have a female cat, between 10 months and 1 year old. She was always super active loving to run and climb. Had her spayed about 2 months ago, unfortunately she cane back with a cold. I gave lyzine and it cleared up. She was behaving as usual for about 4 weeks, then suddenly she stopped going outside, and mostly stays on my bed. She doesn't go far, she can , but does not like to jump any higher than my bed. Seems like she is weak in her legs maybe and her claws get caught on stuff almost every few steps, and it seems like she can't let go(its usually just one claw on a paw when it happens.) she doesn't really seem to be in pain when I feel up and down her legs and her feet, and she is not grouchy. She is definitely not herself. She will jump right up to play withe a laser or string if I wave one but again has a hard time cause she gets stuck. I don't know what to do. Oh, also, she still uses the litter box just fine.
