@njtodctode, I concur with John’s direction above. I have degenerative disc disease along with PMR and honestly didn’t believe my PMR diagnosis. I have significant back spasms and believed that it was more of a reflection of DDD than PMR but my rheumatologist gave me some printed research that indicated that many people have back spasms as part of PMR. I have also been informed that some people are just more aware of the spasms and can distinguish them from other pain. I think that is likely true for you and I. I had initial relief at 15mg but pain returned and I had to bump up to 20 mg and ultimately to 25mg to get relief. After 2 weeks at that level I was able to taper down to 22.5 and now at 20 mg. I taper to 17.5 mg tomorrow. Prayers for relief, peace, and direction for you!
