Strep rash, alergic reactions..ADVISE? - strep rash for 2 months

My son (almost 2) had Rahs funky spots on his legs since March. It began in the legs, arms, back ... But now, basically just the legs, feeling his arms are like paper remains. My daughter had strep, but neg test for this, but gave him medication, received a antibitoics different drugs, creams, ontiments, cream eczema ... And nothing .. some of the doctors in the office saw. Day of stained lost seom go when it seems that an improvement, but then turned back on. It is well and happy, and there are no expressions of others. A dermatoligist can not see for months to the weary, their doctors do not know what it is not clear. In fear that if you get them scars. Should I Hospial the kids here for more information? At 4 dr / 5 times ... WeDetergents have been changed to free dye, etc. ....
