Severe low back pain. can't take anti infams, make me swell up really bad. hydrocodone doesn't touch it, only stops my system up. what can help?

Exercise, tens, lido: Strengthening your core offloads your back and reduces pain. Tens units help reduce spasm, Lidoderm patches provide local analgesia; Lyrica (pregabalin) or Neurontin provide neuropathic pain relief.

Evaluation: You need evaluation by neuro surgeon and if surgical treatment is not an option, physical therapy and pain physician could help.

Core Exercises: Typically core strengthening exercises are the best to help relieve pressure and forces in the spine. I would try and google some or look them up on youtube to see descriptions. If you can do them yourself, wonderful otherwise ask your doctor to get a referral to a good physical therapist for further assistance.
