Im 23 weeks pregnant and in pain ?

My are so painfull and have been on and off for the last 3 months, this last week though they feel like they are on fire, i have tried ice packs and warm showers tey only offer relief while im using them, i am leaking colostrum, which i know is normal, and the only time i seem to get relief is when i touch/squeeze them gently, i know that some people say dont do this because it can bring on preterm labour but im wondering how some mums that are still feeding there previous child dont go into preterm labour. Please i need any real advice i can get, im at the point were cutting them off would be less painfull. Thats was the first question heres the second, my back in the middle to the left of my spine (could be the ilius but close to rhomboid to) is excrutiating and getting worse to im a mage therapist so i know how to relieve that pain (usually) but it seems no matter what i do nothing will make that pain go for longer then 5 minutes either. i feel like im just being a sook but believe me this is terribly painfull and i have 2 children (one of each so cant blame the ) and neither of them gave me these symptoms, thankyou in advance for your help.
