<s>[INST] I am having twitching near the spine.   Dizzy, fatigue, lightheaded, anxiety, and hard heart beat.   Have a history of PVC'S.   I have been to the ER and chest CT scan and X-ray were good.  All blood work was normal.   Have degenetative disc disease in L-4 L-5 and S-1.  Twitching and slight pain comes alittle higher around the kidney area. [/INST] Hi, Thank you for posting your query. Twitching and back pain may be related to L4-5 and L5-S1 disc prolapse with compression of the lumbar nerves. You may benefit from gabapentin capsules, in addition to back extension exercises. Please get back if you require any additional information.
