[|Human|] I am experiencing an itchy itchwhich is most present on my upper chest.  I have some red itchy areas under and down my upper arms, too.  These are red bumps.  I have had a trial on antibiotics for 10 days.  I also took 20 mg predisone for five days.  I thought it was licked, but it has returned this afternoon after I had mowed my lawn.  I take aqua aerobics three days/week.  I wondered if the boron from the pool might be part of the problem.  The rash seems to be isolated to the upper chest.  I have recently showered and used an itch lotion.  It has tree tea oil in it.  It helps.  I do not know what else to do?
[|AI|]  Hi, Thank for choosing Chat Doctor, You have not mentioned for what purpose you took antibiotic, the antibiotic itself some time causes allergic rash,your rash is not generalized, it is limited to certain areas only, this could be non-specific local allergic reaction, may subside itself without medicine, over reaction to this could worse the condition, wait and watch is the best way, taking steroids for this is too early,,, at the most second generation anti histamine can be tried.
