I have had a mass on my spleen for a long time. It measures 10.7 and 9.3. for about 3 or 4 weeks I have been having pain on my left side and it hurts terribly. also starting yesterday, I started getting spasms in my back above my lower back. today I have been in severe pain all down my back. I don t know where it is coming from but it really hurts and my dr is booked up and cant see me. can u please help me figure this out.

### output:

HI, Thanks for asking. I understand your concern.  You have left sided back pain severe enough to disturb you. After going through your information I feel the cause of such a pain in your case seems to be- - A simple sprain of back muscles. Which will resolve with home care suggested in the end.  - Pressure symptoms of the splenic mass you have. IT is pressing on the nerve supplying middle & lower back & causing the pain.  - Another logical possibility the considerably big mass stretching the line of gravity in front. While the back muscles pull it back to maintain equilibrium. The muscles are thus over strained & get painful.  - Nerve root compression at spinal level due to inflammation degeneration of vertebrae/ inter vertebral disc can lead to such pain.  * You need consultation of a gastroenterologist/ orthopedic surgeon. MRI of the part would pinpoint the cause . This will follow specific treatment.  Till then, you can try. Taking rest/ applying muscle relaxants locally(no massage please)/ pain medicines over the counter/ avoiding bending or weight lifting while you can get appointment of a doctor/ If the pain is unbearable go to ER for preliminary management.  Thanks.
