Question: Hello, I may have been bitten by a spider on my chest 3 days ago. I have dizziness when standing or sitting, and have had no energy for 2 days. I have slept from 12pm to 5pm, then slept from 6pm until 7 this morning, and still feel tired. No fever, and just a sore red spot on my chest. I was also stung by a yellow jacket wasp on Tuesday.

Detailed Answer:
Welcome to HCM. These are very well symptoms that are associated with anaphylaxis. Even thought the benadryl should help, remember that it is also very sedating and may make you very sleepy. SO depending on how many benadryl you took and how sensitive you are to medications, some of this fatigue could be the benadryl. I would increase your fluid intake to help with your dizziness, drink plenty of fluids and you should start to feel better in a couple of days. Good luck.

I am 59, and recently had surgery to remove a very large lipoma from my back. The surgery was done in an operating room due to the large size of the lipoma. I have a severe allergy to latex - type 1 IgE mediated with anaphylaxis, and strict latex precautions were in place. I also have severe asthma secondary to the latex allergy. I do have diabetes - type 2 insulin dependant, and I am post graves disease. I was intebated. When I was extabated, I had trouble breathing. The Anesth gave me an updraft of epinepherine, and I turned blue, and my O2 sat dropped to 70%. The epi was stoped and I recovered, but had severe chest pain. I was admitted and had the chest pain again the following morning. Evidently I showed an atypical rise in my Troponin T levels, with a negative CKMB. I also had some EKG changes. I was transferred to the large medical center, and was evaluated quite extensively - all was negative (stress echo, nuclear stress, )no angiogram was done. I was on a nitro drip and also on heparin IV. Nothing showed except this elevated troponin t level, and they discharged me without a real diagnosis after 24 hours. What do you think happened to me? Could it be related to my latex allergy? ? histamine release?? My tryptase level was 18.5 Could I be allergic to epinepherine? I also showed some fluid around the heart - ? why?

A couple of weeks ago I started passing blood in my stools - quite a lot and went to the doctor who has referred me to a specialist who is going to carry out an endoscopy to see what s happening. Today, I am having severe pain when passing urine and there is blood everytime. It is so painful, I am drinking plenty of water and cranberry juice. Whys is this happening? I take 1 dose of antihistamine per day for my allergies. I am 55 yrs old, female, 5ft 7in and weigh about 15 stone. I am in a very stressful job trying to meet tough targets in the property business. Can you help? (not with the targets, but my health. Many thanks J

While traveling last week, I went into anaphylaxis after eating calamari. Along with eyes, nose, lips, and throat swelling, I vomited violently for hours and had severe abdominal distress. When I finally had a bowel movement, it was followed by bright red blood. I passed blood multiple times. After examination, the ER Dr. said the blood was likely caused by diverticulosis and I should follow up with my GI Dr. My question: Can Anaphylaxis cause acute diverticulitis?
