Phil... yes, indeed pain killers are just a stop gap. Mine started from the chest infection which had me beating up my abdo and eventually the hips due to the coughin pressures. Then I ended up with 2 teeth infections (both extracted a week apart) and had to get on the Ibuprofen...
When I went for my second extraction the dentist (rightly so) pointed out that I'd probably overdone it with the ibuprofen. You see, any drug that can take away a symptom can also cause it. So quite possible the extra dosing (much needed to reduce the inflammation in the mouth pf which I even tried to self extract briefly

) probably had an opposite effect to the good ol back.
Inflammation is a right old pain in the bottom is it not. I can actually feel the random firing of the end of the nerve (it's aassive bundle of electric is how I think of the sciatic nerve - like the main livewire in the house). Still working on it and thankfully - some might think I'm daft - I've continued going to work and managing some pretty hefty patients/clients
You lot have given me the encouragement I needed to hear to get out on the bike (mtb) tomorrow for a 10 miler steadily hopefully.
Looking forward to hearing more and yes, already started working on that bloomin muscle (the horizontal piriform) and the big butt muscle around it to strengthen/stretch the both.
