... calves that are keeping me from sleeping. Is this to be expected? Knots everywhere in both calves. No other side effects as of yet. Is this something I need to let my provider know about? It hurts like crazy and I need to sleep. Anyone have this issue? Even when the muscles aren't "charlie horse-ing" both are tight and feel like Im constantly teetering on the edge of another round of muscle contractions. Any insight will be appreciated... Thanks in advance!
