Hi sorry to hear this, maybe try contact out of hrs GP to get the ball rolling. 
I wonder if anyone has similar symptoms to myself ? 
I have constant pain a feeling like my skin is ripping underneath going from my lower rib on right side under breast and spreading around the back which I think is also pressing on a nerve due to pain also travelling down to my right buttocks and right heel. I had a ultrasound back in February and they found a lump measuring 3cm by 2cm and was not concerned. But 4 weeks ago the pain was so unbearable and I'm taking 45mg codine 300mg Gabapentin plus top up of ibuprofen and paracetamol that the GP examined the lump and sent me back for another ultrasound and the lump is now 10cm by 7cm, and I've been referred as urgent 2 week pathway for cancer specialist to check what's going on, but due to the pandemic my urgent appointment is last week in may so I'm 8 weeks waiting to find out what's going on and a nervous reck in constant pain :(  

I hope you find out ASAP.
