Why do I have this terrible itching (without rash, dry skin or allergies)? I am a 59 y/o woman in OK health, no real pre-existing problems. However in the last 6-8 weeks I have had the worst itching of my life. The way it starts is it feels like a bad mosquito bite, but once I start itching, it multiplies exponentially! I feel like I could itch it down to the bone...and I don t break the skin itching, but I am leaving multiple bruises from itching! There is no rash, and as far as I can figure, nothing that can be attributed to allergies. I m not an allergy prone person. Called my doc, he ordered a Free T4, to see if it was my thyroid (I have a history of low thyroid, having 1/2 removed for a goiter 38 years ago). I rec d letter from the lab/dr saying it was fine, altho it said it was .36 in a range of .47-1.4..?? I ve been suspected of having RA but blood tests do not support it, but I have fairly severe joint pain from something- either arthritis or fibro, for which I take close to maximum amt of tylenol or ibu, and current Etodalac(24hr) and I know that s not good for me, but I need to function! Not sure if relevant, but I also tend to have low platelets running below 100 or so...that s been checked for anything serious 2 or 3 years ago and it s fine. All else is fine with me. Please don t tell me to go see my doc, he s hard to get an appt with, and I have to go out of town in the morning and will be gone for 2 weeks...so I happened on this site and thought it was worth a try-I really hope you can help me! thanks.
