A MGteam Member asked a question 💭
Grantville, KS

It has been very hot where I live and my symptoms have been pretty severe when I go outside. The temperature finally cooled down, but it brought rain and a pressure change on that day, and I thought my MG symptoms would improve with the cooler temperatures, but instead they were much worse......any activity I tried to do caused racing heart, tight chest, short of breath, very dizzy, postural intolerance, pressure headache and heavy/weak legs. Has anyone else experienced this?

My mini migraines feel like lightening bolts to the left side of my head and my eye. Each one feels like I got sucker punched and leaves me numb. Barometric pressure does it for me now. It use to be the sunshine only. Now this. Thankfully I keep my shades close by and just lower the blinds, close the curtains and turn things down, it cools off my everything for as long as I need to.

I know I don’t do well in the heat and if I get overheated at work I bring my neck cooling fan and it helps me a lot.

Humidity makes my vision super bad. Air pressure changes sort of do.

What a frustrating experience — just when cooler temps should have brought some relief, your body had other plans! The symptoms you're describing, particularly the shortness of breath and tight chest, are worth taking seriously. Please contact your healthcare provider about these symptoms, and if breathing becomes severely limited, seek emergency care immediately. Heat is a well-known trigger for worsening MG symptoms. Researchers believe heat may interfere with the signals between nerves and muscles — and since MG already affects that communication, heat can amplify symptoms significantly. Hospitalizations related to MG actually occur more often in summer months. As for barometric pressure changes specifically, while the research on MG and pressure changes is limited, other MGteam members have reported that weather shifts — not just heat — seem to affect their symptoms. You're definitely not alone in noticing this pattern. Some practical tips that have helped others manage weather-related symptom flares include:

- Staying indoors during extreme weather of any kind
- Using air conditioning or fans to regulate temperature
- Keeping crushed ice or cold drinks on hand
- Avoiding strenuous activity that raises body temperature
- Resting and reducing energy use when symptoms spike
- Listening to your body and acting before a flare worsens It would be really worthwhile to track these weather-related patterns and share them with your care team. They can help create a management plan tailored to your triggers, including weather and pressure changes.
