Got a rash on my neck about 1 May when the weather warmed up. Suspected heat rash.
Used OTC cortisone cream which didn't help much.
Suspected lice or bedbugs.
Washed all bedding and clothes in hot water and scent free detergent.
Went to see Dr Mike Wilson ~15 May.
He gave me a shot of cortisone and 5 days of prednisone.
Rash came back about two weeks later.
Stopped using the towels at the pool.
I tried to let it burn itself out but it spread to my chest and back.
Went back to Dr. Wilson June 15th and he repeated the treatment.
Stopped going to the pool June 14th. Didn't help.
Pool people said no change in pool chemicals.
Rash came back earlier this week.
