Thanks for the query to H.C.M. Forum.
Please note down one thing that BACLOFEN
is not a treatment for muscle spasm , rather this is a pain killer and muscle relaxant
Why , there is spasm or pain in muscles , assess this thing.
hperkalaemia ( potassium )
Vitamin E deficiency ,
anemia , calcium deficiency
are few reasons for leg cramps
Over exertion and fatigue are other causes.
Consult a physician and get his opinion with complete blood examination .
