Hope he's caught it early. DH had singles two years ago mid-May. He didn't say anything to me until he was already scabbing. He ended up on such heavy-duty pain drugs that he lost 6 weeks of time that summer. When he got well enough to realize the drugs were making his thinking fuzzy he quit taking them. Went to Tylenol and gritting his teeth. Hates being 'drugged'.
It was late September before he felt better.
