I Have Osteoarthritis In My Spine From Lower Back To

I have osteoarthritis in my spine from lower back to thoracic region with significant compression of discs at L3 & L4 with exposed nerves. I am allergic to all forms of salicylates. My doctor has prescribed Lyrica for the nerve pain I experience in my legs (stemming from exposed nerves). I have read all the side effects on here and feel the most common side effects are too scary to proceed with this treatment. Your opinion please. My current pain relief is Endone, Codalgin Forte and heat.
Apologies, did not realise had to pay for this service. Cannot afford as on a pension. Will check with a local doctor other than the one who has prescribed. Thank you
