I occasionally experience numbness in my hands, and tonight my fingers on my right hand were weak to the point of not feeling comfortable picking up a glass of water, as it could topple over in either direction. I also noticed occasional word substitution when writing, such as using 'on' instead of 'or'. I am 69 years old and concerned that these may be early signs of a neurological condition. Can you help direct me to the proper specialist and provide any insights on what might be happening?

Two big toe nails on my feet turned yellow color. The discoloration occurred the day after I applied spray tan, and the color becomes brighter after wearing closed-toe high-heeled shoes and tights at work, then fades when exposed to fresh air. I'm unsure if this is due to the spray tan or a fungal infection. Please advise.

If you and your wife are in a monogamous relationship and both test negative for STDs, is it possible to catch an STD from each other? She has had a cold and sore throat for a week now and is afraid that she might catch something that could be transferred as an STD. Is there anything to worry about?
