I got an insect bite whilst on holiday over ten months ago. It became infected and swollen so I got antibiotics when I got home and it healed over, leaving just a small scar. However, I have noticed that it has recently become very itchy which I can’t understand why. Can you help?

This is to do with the nerves regenerating under the damaged skin. It's a good sign! Although undoubtedly annoying at the time, it just means that the skin is coming back to normal status. Also, some skin cells will be regenerating as normal skin instead of scar tissue, and this can itch too. Drink lots of water, take vitamin C (which is also great for collagen building), use nettle tea or tincture to prevent uric acid exacerbating the problem, and maybe apply Comfrey Cream to speed up the renewal process.
