Slader,
Take it easy...easier said then done.
Yes, when I overdo it, the tendons feel like they have been overstretched. Even hard to get into bed. Leg feels like it weighs a ton. Sometimes have to have help lifting the leg.
Fortunately, after I rest, elevate and ice, it feels better. Sometimes I have to take a pain pill. Ibuprophen still isn't helping yet. Doesn't give any relief. Hate that I have to depend on the stronger stuff to make a difference. Don't like taking them, certainly don't want to get addicted.
Do you have a sit down job? Sometimes sitting too long causes pain and discomfort. Surely is the cause of stiffness.
Rest more often. Again easier said then done!
Blessings,
