Just got told I might have psoriasis or eczema. I'm in rsp currently and don't ship for basic until january what should I do?

Give your Recruiter the heads up. But you will need to have a definitive diagnosis.

Per the DoDI Medical Disqualifying Conditions:

5.21. SKIN AND SOFT TISSUE CONDITIONS.
a. Applicants under treatment with systemic retinoids, including, but not limited to
isotretinoin (e.g. Accutane®), do not meet the standard until 4 weeks after completing therapy.
b. Severe nodulocystic acne, on or off antibiotics.
c. History of dissecting scalp cellulitis, acne inversa, or hidradenitis suppurativa.
d. History of atopic dermatitis or eczema after the 12th birthday. History of residual or
recurrent lesions in characteristic areas (face, neck, antecubital or popliteal fossae, occasionally
wrists and hands).

and

q. History of psoriasis excluding non-recurrent childhood guttate psoriasis.

If none of the above apply to you, then you should be good. Either way, give the heads up to your Recruiter.

Some more information since its probably pertinent they said it is probably caused by stress and the rash itself was scaly, bleeding, and had a clear discharge. Is this going to be disqualifyying or require a waiver since it is something that will most likely come back
