skin allergy due to use of anaesthetic cream

I am 43 year young married guy.  Two years back I used some anaesthetic cream (lidocaine/xylocaine based) cream for delaying ejaculation during sex though otherwise I am OK but still wanted to enjoy more time.  I used to apply this cream on the head of the penis...after using for about 6 months or so I started feeling some itching problem on the body..when I contacted my skin Dr. he told me its nothing but some allergies and fungal infection...after taking some medicines (Tabs. Teczine & Neoloridin and applying some local cream on the affected parts of the body) I was fully cured but when I stopped using these medications..I started again experiencing the same problem...Now again after stopping the treatment I found some small bumps on the front side of my shoulders (neither painful nor having some liquid)...Again when I started using the same medication for about a week now..I have seen a tremendous improvement...I am sure after taking the same treatment this problem will be subsidized...I want to know whether this allergy or whatever is due to that application of that anaesthetic cream or something else and whats the proper cure/treatment for this problem...

Hi,
Allergies are your body's way of reacting to perceived threats in your environment. When the body is exposed to a substance you are allergic to, called a trigger or allergen, your immune system tries to fight off the assault by producing an antibody called immunoglobulin E (IgE). The problem is, these antibodies cause your cells to release proteins called histamines, which in turn can cause itching, swelling, runny eyes or nose, or, in more severe cases, problems with swallowing and breathing.
There are hundreds of different allergy triggers, but the most common ones include pollens, molds, dust mites (tiny creatures that live in household dust), animal dander, and industrial chemicals.
Your doctor can help determine whether you need an over-the-counter (OTC) antihistamine or the prescription variety. Although the older OTC drugs, known as "first-generation" or sedating antihistamines, may cause side effects like drowsiness or anxiety, newer antihistamines are much less likely to when taken at the recommended dosage.
Your doctor will consider allergy shots if your symptoms don't seem to respond well to medication or if you have year-round allergies and prefer not to be on medication all the time. Medications can control symptoms, but allergy shots -- if they work in your case -- are a more lasting solution.
