So I'm finishing up my first week of PCT and i am getting excruciating back pumps in my lower back. Just above where back dimples are. It's so bad I have to stop walking and lay flat somewhere. I can't even do stuff around the house or with my kids without being in horrible pain. I never got one back pump while I was on Havoc cycle. Anyone know why it's happening now? I drink tons of water and take literally 12 Torene tablets (500mg each) per day. Torene helps but only for a couple of hours. Thanks.
