Why am I suddenly getting huge lumps when bitten by mosquitoes?

Because they are infected. I go like that from bites. They end up looking like spaceships on your skin. Do you take allergy pills?

Are you sure you’re being bitten by mosquitoes? Last summer I had the same thing happen to me and I was wondering if I’d suddenly developed an allergy to mosquitoes, but it turned out that I was getting bitten by yellow flies (well, at least that’s what everyone keeps telling me based on the painful, itchy bumps they leave behind, though I’ve never seen one myself).

Our allergies can get worse or lessen as we age. As we get older our skin doesn’t bounce back as quickly either and our immune to different allergens changes.
It could also be horse flies or ant bites or as suggested the yellow flies. I have them here but they don’t seem interested in me.

Try not wearing anything scented or eating bananas before you go outside. It will lessen the amount of bugs attracted to you. Also heavy lotion seems to also work as a deterrent. Contrary to popular belief, bugs prefer clean, non greasy skin. It is why skin so soft works to keep them away as well. They also don’t seem to care for salty skin.

Whenever I go to the beach, I take a dip in the water before settling down on the beach. It seems to keep them away. I’m assuming they don’t like the salt from the ocean.

Here’s my input as to why the bites are worse then you remember:
Age difference
Medications you are taking
Different bugs
NEW allergies.

It sounds ike your allergy is ramping up. That happened to me a few years ago. Caladryl is your friend.

Partner is picking up some Benedryl.

Ummmmm…...and I thought it was just me. Though sometimes it was those bloodsuckers biting me several times in close proximity to the 1st bite, so when it swelled up it was like a super bite. They do last longer unless I quickly dab them with rubbing alcohol. Since I started using Coleman Max Insect Repellent, it is if I have a Klingon cloaking device about me. Being 98% deet it keeps those bloodsucker at bay!

@Mama_Cakes Caladryl goes directly on the bites. Stops the itching for several hours.

You’re probably becoming more sensitive to the venom as your exposure to it increases. I realize this is counter-intuitive, generally reaction to a toxic substance decreases with increased exposure. But in all likelyhood this doesn’t hold true in continually interacting, biologically evolving systems.
Wearing a really good insect repellant whenever you’re out in the woods or at night is the best idea.

Possibly chemicals to treat mosquitoes .
Cities now use strong chemicals ( not sure if DEET is still used) to spray infestations.
(Ex; ponds, parks etc).

I agree with @jordym84 that possibly it isn’t mosquitos.

It is true that we can develop allergies over time. Our bodies can decide something is bad and start sending out more fighter reactions that cause inflammation. Unfortuneately our bodies get better and better at recognizing and reacting to the antagonist, which means the body actually gets better at sending out fighter cells.

I would just put topical benadryl spray, calamine lotion, or cortizone cream on them. I never take a pill. But, I hate taking pills.

If the area of redness is growing that can be cellulitis. If it is getting bigger and bigger and it is very uncomfortable, not growing round, but towards your heart, that is a clue, or if there are red streaks coming from the area. If you aren’t sure you can draw around the edge of the red area with a ball point pen. Cellulitis can grow a centemeter every 12 hours or faster. It must be treated ASAP. But, if it is multiple bites reacting, then it is unlikely it is cellulitis or infected in any way.

And, buy some repellent, and I am sure you know this, dress with long sleeves and slacks from dusk throughout the dark hours. If yu are walking through the woods and grassy areas consider wearing closed shoes and tall socks to protect your lower legs. I know that sucks in the summer. It could be chiggers or some other bug.

I found a couple of new products citronella bracelets were one, that I thought appealing. There was another brand of friendly yet bug dope that blended extracts from plants that secrete anti mosquito smells that I liked. But it is in my car and forgot the name. I just sat down too. I’ll try to come back with it later.
