terrible calf pain

Meredith
I'm about 7 weeks and both my calves hurt so bad I am hobbling around and can't really walk. I went to a barre class two days ago and did some calf work but this seems insane and like nothing I've ever experienced before. Since it's both calves I'm assuming it's not a blood clot? But what's going on?! And how can I make it stop? And what medicine can I take? Thanks in advance!
