3 months post C-section

I just suddenly feel like my joints ache more and I'm needing to cut back on my walks and baby wearing. I'm feeling more depleted now than at the 2 month mark even though I'm now 3 month post C-section. Anyone feel similarly and have any tips that made them feel better? It seems like bad timing since I'm headed back to work in a couple weeks but maybe that will make it better since I won't be lifting the baby all the time? Posting here because I've heard breastfeeding makes healing slower.
