HELP - Lost water pressure to shower after turning off water to house
I turned the water in my off house because I was going out of town for a week and didn't want a pipe to burst due to the cold weather while I was out of town. After turning the water back on, I have very little water pressure coming out of the shower head in my main bathroom. The water seems to be fine to everything else, including the shower head in the basement bathroom. The shower head that is not working is only a shower head (no lower faucet for a tub). I've tried turning the supply off and then back on again. After doing this, the shower sprays normally for a couple seconds, then goes back to very, very low pressure. I've also tried running the shower for a minute, it stays at a fast drip. Any advice given would be very appreciated.
