I spent a couple days going up and down flights of stairs moving. now i can hardly walk, with my calves so sore. what can i do to unlock my calves?

Leg pain: Elevate, ice and rest. Taking Ibuprofen will also help. All the best.

Sore calves: For musculoskeletal pain consider NSAIDs, an epsom salt bath, massage, warm soaks after 24 hours. Rarely there may be clot ( very rare if both calves-but usually anterior thighs hurt ) but consider urgent care/ER/doctor evaluation to evaluate for the rare possibility of clot,especially in smoker( which should be done today).Also evaluation for claudication.
