1 month old crying all the time. Fever.

Hello, my 1 month old crying all the time. There is no particular time as she cries all the time day & night. We are giving her 60-90 ml formula feed and she does 6+ wet diapers and stools are fine. She passing gas all the time. She cries all day once wake up so we make her sleep but she wont able to take a nap more than an hour and then again keep crying. Medications so far: We thought it may be silent reflux and giving esomprazole but it is not working. We thought as colic but she is crying all day and night but still on paed recommendation we giving neopeptide and its not working. Neosporin for any congestion as well. We have switched 2 paed. So far and no result. Currently doctor has suggested to use protectis probiotic drop and switch formula to similac total comfort. It feels like she is in pain all the time while she has been checked for physical pain as well. She cries so hard.  Please advice or suggest us what should be done next. Also she has no fever.
