Disc protrusion is a condition, which can arise due to many reason. According to your calculation, all these started at around 39 years.But i would still think, it was diagnosed pretty late. We see disc protrusion at pretty young age-say 25-30 years age group.Its all related to the type of work we do. For eg- Too much sitting without break, or bending or lifting heavy weights can cause this problem. Also it may be due to stress activities, improper sleep, bad posture during driving, etc.
Also few people have connective tissue disorder, which causes disc degeneration too early.
Try to do a lot of Lower back and neck physiotherapy for this.I should really help you.
Need to supplement the physio via medicines (Muscle relaxants).As far as Glucosamines are concerned, they can only prevent the speed of degeneration.And they have to be taken for a lot of days, before any active results are obtained.
Regarding the Thyroid problem, am really sorry, but the real cause of it can't be explained.You should consider yourself lucky, as it was ruled as benign.
Feel free to ask more in this context.
I should be called "feellikegreatgrandpappy" I'm 62 going on 90! I started with the neck and back in my early thirties. Also had hashimoto's- and had half my thyroid removed, the other half must have removed itself because it's no longer there! I also have diabetes, gluacoma, cataracts, osteoarthritis in most of my joints (can't take meds for the pain because of kidney desease) , a temporal lobe seizure disorder, kidney failure, thirteen surgeries, high blood pressure and cholesterol and yes, an anxiety disorder with panic attacks.
But I made it this far and don't plan on giving up. It is tough, but if you get in some good habits like diet and exercise life will probably get better for you. Some people like us were just born on the wrong side of the gene pool :o) This may not have helped much but I love humor and humor does help take my mind off of the pain! Rich
