I know that horrible feeling of muscles in spasm all too well, my upper back, neck, abdomen, legs as well as lower back all have their turn at going into spasm at times and sometimes there seems to be no rhyme nor reason for it. I find Baclofen to be a great help in those times, have you tried it?
I know what you mean by Cofwa being a bit depressing, it's good to hear others stories but all the terrible suffering of others gets me down too. Its good to know its there though.
Have you been getting worse for a long time or do you think this could just be a 'bad spell'? I've been suffering more recently and believe it's possibly down to the weather. I'm going to buy an electric blanket soon! Do you take a large cocktail of meds? I'm also on Dihydrocodiene, Diclofenac, Gabapentin (lifesaver!) and Baclofen all for pain and Docusate sodium (constipation) Omneprazole (Stomach ulcer caused by Diclofenac!) and Venlafaxine(Depression). I keep hoping there might be new drugs coming along to better help the pain etc but they never come. Have you found any that really help? Have you thought about the Stimulator or pump?
