Can increasing hip and abdominal pain and abnormal blood reports indicate any severe conditions like multiple myeloma?

Hi doctor,

I have been experiencing symptoms like nausea and vomiting over the past year, and it has been progressively getting more frequent. I have had persistent, sometimes debilitating, pain in my hip area for the last few months. X-ray and scans so far have revealed nothing. I am often very fatigued and have pain in my abdomen. Based on the tests that have been prescribed to me, it seems as though they may be looking for multiple myeloma. My current medications are- tablet Hydrochlorothiazide 25 mg, tablet Nebivolol 10 mg, tablet Amlodipine 5 mg, and tablet Estradiol 2 mg. I have been getting blood and urine tests ordered by my PCP and now a hematologist due to the symptoms, which have been steadily increasing over the past year. The out of range values from the latest test are as follows-

ALT- 68 u/l.

AST- 53 u/l.

Beta 2 globulin- 0.8 g/dL.

Immunoglubulin A- 906 mg/dL.

Kappa light chain, free, serum- 44.6 mg/L.

Lambda light chain, free, serum- 33.6 mg/L.

White blood cell count - 11 thousand per uL of blood.

And in case it matters - IFE interpretation- Normal pattern. No monoclonal proteins were detected. Even though my results are in, the doctor will not be going over them for another week or two. Based on an internet search, it seems like they may be looking for multiple myeloma, but I am just trying to get some kind of indication of what I may have? I am looking for a second opinion from you. Thanks.
