I'm married and have not had sex with husband for 1.5 years. So on a crazy girls trip away we drank too much and I ended up sleeping with a man from London. This was 12 weeks ago. I've been having very high anxiety over the fact that I could have contracted something from him. The last couple of days I have had some nasal congestion in the morning and night. Also I've been feeling slight sensations in my hands , back, legs. I'm not tired .. In fact with anxiety over this it's been hard to sleep, and I haven't felt other symptoms. Are these symptoms and should I be very worried?
