There are several potential causes here. One would be poorly fitting undergarments. For example, if your bra is too tight it could compress small nerves in the breasts leading to a sensation of discomfort or tingling
Another possibility would be irritation of the skin on the breasts from excessive sweating. This is a pretty common problem in the hot summer months. Usually the skin has a reddened or chafed look to it. This can be prevented by wearing light wicking clothing and by keeping the skin dry and by using a good skin moisturizer.
Another problem that is common in hot and humid weather is a fungal infection of the skin. This usually occurs under the breasts, where the skin may be reddened. This can be treated with good skin hygiene and a topical over the counter anti fungal cream.
Another possibility that I can think of is shingles, although this would be unusual in an otherwise healthy person your age. Shingles is basically a reactivation of the chicken pox virus (so you would have had to have had that at some point) and in the early stages of reactivation it produces a painful or tingly sensation in the skin, although usually just on one side of the body.
