Please do not take things otherwise. Investigations are indicators, no doubt presence of RBCs is alarming but we need to go for further diagnostic examinations. It could be possibly due to Renal Stone, Urinary Tract Infection
etc. so there are many conditions which could be possible but the information you have given according to me is suggestive of either Renal Stone or Urinary Tract infection.
An episode of first pain does not rule out Renal Stone, so do not panic, just consult your doctor and have to go for USG abdomen. Have plenty of fluids, do not start Beer( as could be recommended by friends for stone) until and unless agreed by the doctor. You may opt for Homoeopathy if you have a doctor available.
Feel free to ask questions
Wish you a speedy recovery to health
