Welcome to JA and thanks for this question. im sorry to hear about your symptoms. Actually a medial branch block can certainly be an effective method to control the pain in your situation. It can also control the muscle spasms and the cramping that you have been experiencing. The reason being that these muscle spasms and cramps usually occur because of nerve compression which is occiurring in the spine and that can also cause some portions in your legs and surrounding regions to be extra sensitive to touch etc. This is why a medial branch block can take some time to determine where exactly radiofrequency ablation can be done. The medial branch block can be done a few times until the exact region of the problem is identified.
But to answer your question, YES medial branch block can control the spasms in the short term and radiofrequency ablation can also control them on a more permanent basis.
Regarding the spasms during healing, YES there can be muscle spasms during that time however afterwards the spasms do stop and once they do, your current problems with reccurent spasms and pain should be solved effectively.
You can have your doctor start you on muscle relaxants to control the spasms in the meantime, these could include drugs like flexeril or tinazdine. These can control the spasms in the short term until the radiofrequency ablation can be done.
Do you have any more questions?
