Hi Val, so it sounds like muscle soreness and not joint pain, but I am not able to tell for sure just from our exchange here… Muscle soreness usually comes from working the muscle harder than you have in the past. Muscle soreness can also be a response from those muscles, contracting to protect a major joint (or joints). In either case, I would advise to not stretch, as stretching might feel good in the moment, but it could actually cause further “damage”. Therefore I’d let it rest to recover.
More often than not it simply means that you need to strengthen those muscles. But again, it is not possible for me to assess with accuracy what exactly is happening in the joint/muscles…
