Cramps

Hi Momshies.. Lately I've been experiencing leg cramps. Sobrang sakit. Yunh effect nya lasts for days. Kaninang morning nagising ako sa sakit dahil naninigas na yung right leg ko. Up till now naninigas both legs ko at mahirap maglakad. Pero nakakapaglakad ako. Any ideas bat ngyayari to? Or anyone experienced this? Thank you!
