Hi Katie,
I found that oral baclofen did help (10mg) but I also had an allergic reaction to it so did not take it for the next 7 years. Then the spasms and spasticity became intolerable & now I have a baclofen pump. After the pump was implanted I went from 24 hr continuous intolerable pain (beyond 10/10 spasms in the foot, leg & pain on surface of skin) to 80% pain free in 12 hours. After 6 months I lost the dull ache in buttocks & thigh, the stinging hornets & pins & needles. I am now totally pain free for the first time in 12 years so it definitely is cumulative. I am sooo happy. Spasticity is about
60% better & could be much better if I could tolerate a higher dose but it makes me shake, thoughI have found exercise has improved this enough for me to increase the dose a bit.
Try a high dose of baclofen & physio and see if that helps. The neuro explained that the exercise is very NB because the more the muscle tightens the greater the spasm the worse the pain & it becomes a viscious circle. All the best
