About 3 months ago I felt a 'pull' in my lower back (left side) while lifting at work (incorrectly!) and a lump about an inch across appeared at the site of the pain. I had to lift a few more things incorrectly at work because of where they were and how busy the store was. This carried on for about 3/4 weeks so I was re-injuring the area just about every other day.
The lump has gotten slightly smaller, can be moved around a bit and feels as if it is underneath a few bands of muscle. The pain sometimes radiates into my left buttock.
I've been to the doctor, physio and radiologist for an ultrasound, all of whom have different opinions on the problem! Erector spinae stretches I found online stretch right across the area of the lump and seem to lessen the pain for a few days but the lump stays static.
I'm concerned that maybe it was a muscle tear that I didn't rehab properly and scar tissue has formed? I haven't lost any strength in the muscle and can still play sports but have some swelling and pain afterwards. Pressing on the lump in a certain way provides that 'good' kind of pain and a foam roller helped a little bit in the gym.
Any advice/opinions on what I can do to get back to full health would be greatly appreciated!
