I have chronic neck and upper back pain for more than 2y. Also I'm having a lot of sleep problem (Can't stay asleep and not getting deep sleep). feeling tired whole day. Also getting headaches. My pain management doctor ordered MRI and certain blood tests (CRP, CBC, ESR, ANA, HLA-B27, Anti CCP, Rheumatoid Factor), which all came normal. He said that I'm suffering from fibromyalgia and prescribed me Duloxetine 20mg + Pregabalin 75mg and advised me to do some neck exercises. It improved my pain for a period but not my sleep. Later he changed the meds to Desvenlafaxine 50mg + Pregabalin M-75mg, Still no significant improvement. The pain is somewhat bearable after using icegel and heat compression but the sleep problem is what is hampering my daily life. Another thing is sometimes when i take an afternoon nap of an hour, i feel refreshed but i never feel refreshed even after getting 6-7 h sleep at night. I'm a student and this thing is causing severe problem in my study and daily life. Ty
