Advice needed. I had shockwave treatment last week and everything was fine. I was actually starting to feel better! I had my second treatment this Thursday and it hurt more during treatment and now my calf muscle is so tight I can barely walk. Is this the norm? I've tried the massage gun to make it less tight but so far it's not worked. Now dreading next week's treatment!
