Waist pain during pregnancy. Time?

I’m three months pregnant with my second baby and have been experiencing waist pain for the past two weeks. My doctor (gynecologist) has done regular check-ups and USG and everything is good. I told my doctor about the waist pain and she suggested applying MOVE or VOLINI spray but did not give any painkiller or paracetamol for the pain. I am applying VOLINI spray but the waist pain is not subsiding. It is difficult to sleep due to the waist pain. I am taking these medicines: macfolate (once/day), drydosure 10mg (thrice/day), ondem MD 4 (thrice/day). I know none of these help with waist pain. Since my doctor is not giving any pain relief medicine, can you please suggest any OINTMENT that might help to subside my waist pain at this pregnancy time ? Any help is appreciated.
