Enlarged Spleen and left kidney pain.)

I feel like my left lower rib is not normal. I can feel it by touching. I started feeling pain in left chest almst 8 mths back. It got severe after few days. I could feel the pain by taking deep breath. Heart, CBC, BP, Blood glucose all tests done at that time. All gud.  Doctor gave antibiotic, muscle rlxant, antcid and multivtamns. After 10 days, the pain was like suppressed. It did not come back(no severe) but I still feel light pain. I think the problem that time was enlarged spleen. I feel it now. Also, my left kidney area got severe pain 5 days back. I vomited for few minutes due to pain nd I was unable to breathe properly nd not even able to stand on my own. Doctor gave 2 analgesic injection but nothing. At last, he made me sleep by giving sleep injection. No pain in morning when I woke up. Next day pain came back. I still hv light pain. Plz tell me if this is sign of blood cancer. At least confirmed symptoms of blood cancer so daf i can talk to ryt doctor (urolog, or Onco.)
