I have been diagnosed with an 8mm herniated disc between c5-c6. I have undergone anti-inflammatory meds, nerve meds, physical therapy and one injection. Prior to injection my neck hurt, head some and left arm felt like it was at a rave all day long. Post injection my arm has settled but my head and neck are worse. I feel less "with it" as well but I think the constant, migraine like headache is at fault. Has anyone else had this as a major symptom and particularly as well, did surgery help? I was very active before, so being exhausted non stop is miserable. Thank you so much!
