Anti-spasm drugs

Hi everyone, just wondered if theres any medications people have found useful for muscle spasms? Just a reminder Ive not been diagnosed with PD, still dont know whats wrong, I was put on baclofen by my GP on tuesday but my muscle spasms actually got worse, I dont know if its a coincidence or if it was the drug but I was really struggling, I was in so much pain and was finding it hard to move anything so I was told to stop it about 3 days later, vey disappointing. My GP said thats the only thing she can give me, Im not seeing the neuro again til february. Do the general PD drugs tend to help spasms and twitches?
