Recurring Lower Back Spasms

HI All,

I have had 3 prolapsed discs all requiring surgery to remove them from my lower back. These surgeries all occurred over a 11 year period with the last surgery 23 years ago. My last surgery also resulted in them fusing my lower spine due to the fact of recurring prolapsed disc surgery. However, over the last 12-18 months I have had recurring back lower back spasms. I get no warning of these spasms and they can be painful and restrict my mobility lasting anything from 2-3 days to 10 days before they complete go. I am 54 and I am wondering if I am showing signs of some sort of arthritis which could be causing the problem? I will be honest I do not like visiting the doctors and would only go there as a last resort. I keep myself fit but when I have these bouts of spasms it means it does affect my ability to do my exercises.  

I came on here to see if anyone had similar story to me and find out possible causes etc?

Kind Regards

Tom
