hello luis.. as u said ur having low back pain since 1mth ..and it didnt relieve with massage.. firstly just check if u have any history of fall anytime anywhere.. and then your work type which requires more of sitting or standing in one posture most of the time ..or if do u travel more on two wheeler..coz all these might lead to LBA due to muscle strain..you need to take rest for atleast 3 wks for this with medication of analgesics .. it might also b due to any disc prolapse due to any injury, which can b diagnosed with x- ray by an orthopaedician doc.. dont get any massage but betr take analgesics and give rest to urself.. it also happens with age due to wearing of bone density which often requires calcium and vit d supplements.. so first i suggest u to get ur x-ray done and then do accordingly as ur doc suggests.. nothing grave to worry ,,u need to give rest to you back for some period.. take care..
