The ART guy noted tight left and right Piriformis, IT Bands and Hamstrings. The MRI noted hamstring tendinitis.
The bike shop has done bike fits and multiple rechecks to ensure all is spot on.
Both bikes have Specialized Sworks “power with mirror saddle”, one saddle is 4 years old (Roubaix), the other is 2.5 (Aethos).
The bike fitter recommended a 143 saddle vs 155 since I’ve lost 20lbs - sit bones have moved. Unfortunate the 143 saddle aggravate the sit bones. ;(
Currently off the bike focusing on recovery. Thinking about swimming….
Appreciate any help with recovery silver bullets, sworks power saddle, or whatever may help.
Thanks!!
Funny you should mention this...
For the past 4 months I've been dealing with the onset of piriformis sciatica, again... Been some years since last experiencing it.
Recently, when I first felt it happening, it was from riding... At first, I thought it was from a shift in my hips/seat position... I have some scoliosis also.
But after riding a different bike with a different saddle, and not experiencing the issue, I realized it could be my saddle... and years...

I haven't had saddle issues for quite some decades - could ride just about anything, just a consideration for long saddle time comfort...
I currently have 2 dominant saddle types, a slight cradling style with a curved seat profile, whic I really have liked - Spec Phenom.
And a flatter saddle type - Spec Toupe
The Phenom - on 2 bikes - now causes exacerbation of the sciatica.
The Toupe type - on 2 other bikes - works great...
Of course, now that I have that onset, I have to pay attention and deal with it. SO the Phenoms are now 'off' and flatter saddles place on those bikes.
I also can't really do any hard efforts while riding, so riding intensity is out, and even though I continue to do around 1.75 to 2 hr rides regularly, they're steady effort, with recognition to not do any pedal efforts which exacerbate the sciatica.
Also, strong stretching is counter getting it to 'relax'. When I had it bad, some 4 decades ago, the only thing which helped get relief and get recovery was 400mg Motrin 4x a day (prescribed...Ibuprofen).
Currently doing 200 mg 2x or 3x a day, and it is helping, slowly...
Also, I can't imagine going to a narrower saddle is going to do anything to help or alleviate the issue...
Ride On
