Uy, totally normal yan mama, especially after C-section kasi ang dami mong na-experience sa katawan during surgery at recovery, a few of us had the same leg at back pain, sobrang frustrating talaga! Best advice ko is to take your prescribed pain meds on schedule (hindi yung hinihintay mo na maging severe), try to move around gently when you can kasi tumutulong din sa circulation, and use a support pillow when you're sitting or lying down para di kang nakakauntog. But if the pain is getting worse or hindi bumababa kahit after 2-3 weeks, definitely check with your OB kasi sometimes may swelling or complications na kailangan tingnan, better safe na lang kami with post-op stuff!
