Is It Safe To Take Lyrica Over Zydol For Disc Bulges In Lumbar Spine?

Hello. I am a 56 year old woman. I have 3 disc bulges in my lumbar spine plus osteoarthritis, spondylitis and severe fibromyalgia. Is it ok to take Zydol 50mg capsules once daily while on 75mg of Lyrica, taken at night. I also take 50mg of Endep at night. I exercise every day and try to keep my back mobile but the pain is getting worse. Please advise. I would be most grateful for any feedback. Lindy
