<s>[INST] I am having pretty severe pain in my lower RT back.  It started 3 days ago as a dull ache in my RT hip.  It progressively got more intense, and started feeling like I was having back spasms, but I wasnt feeling the typical muscle contractions that would go with it.  Last night and all day today it has been quite severe and when I inhale the pain really gets horrible.  It also seems to pound when my heart beats, like a thumb would after smashing it in a door.  Any inhalations, beyond the most shallow are so painful, I feel like I want to guard that area (which doesnt seem to help.)  I took 8 advil and 1/2 of a percocet today and that brought it down to tolerable, but the minute the meds wear off I am just hurting so bad I can hardly tolerate it...and I have a high threshold for pain.  Any ideas?  Could this be kidney related?  Thanks for your input - Marcia (age 53) [/INST] Hi welcome to Chat Doctor forum.  Thanks for calling Chat Doctor. Forum.  You are having severe back pain on lower right side, started as dull pain in the hip, progressively increasing, increasing with inhalation.  As you have correctly assumed it might be urinary tract related, there might be infection or stone in the ureter at the lower end near the bladder.  Other possibilities are orthopedic or infection of the soft tissues like abscess.  I advise you to consult a urologist for diagnosis and treatment, You may need to have M.R.I.besides other routine tests for confirmation.  Avoid taking potato, other tubers, tomato, and egg till the pain persists.  Wishing for a quick and complete recovery.  Best regards. </s>
